Magneto Optical materials inoreva optical information inoshanda zvinhu zvine magneto optical mhedzisiro muultraviolet kune infrared mabhendi. Rare earth magneto optical materials imhando itsva yeruzivo rwemaziso anoshanda zvinhu izvo zvinogona kugadzirwa kuva optical zvishandiso zvine mabasa akasiyana siyana nekushandisa yavo magineti optical zvivakwa uye kupindirana uye kutendeuka kwechiedza, magetsi, uye magineti. Senge ma modulators, isolators, circulators, magneto-optical switch, deflectors, phase shifters, optical information processors, zviratidzi, ndangariro, laser gyro bias magirazi, magnetometers, magneto-optical sensors, muchina wekudhinda, vhidhiyo rekodhi, mapatani ekucherekedza michina, optical discs. , optical waveguides, nezvimwewo.
Kwakabva Rare Earth Magneto Optics
Therare earth elementinogadzira nguva isina kurongeka yemagineti nekuda kweiyo isina kuzadzwa 4f electron layer, inova tsime remagineti yakasimba; Panguva imwecheteyo, inogonawo kutungamirira kune electron transitions, iyo inokonzera chiedza chekusimudzira, zvichiita kuti simba magneto optical effects rive rakasimba.
Yakachena isingawanzo simbi yepasi hairatidzi yakasimba magneto optical mhedzisiro. Chete kana zvinhu zvisingawanzo itika pasi pano zvadonhedzwa muzvinhu zvinoonekera zvakaita segirazi, makomboni makristasi, nemafirimu alloy, ndipo panobva paonekwa simba remagneto-optical effect yezvinhu zvisingawanzo itika panyika. Izvo zvinowanzo shandiswa magneto-optical zvinhu zvinoshandura boka zvinhu zvakaita se (REBi) 3 (FeA) 5O12 garnet makristasi (simbi zvinhu zvakaita seA1, Ga, Sc, Ge, In), RETM amorphous mafirimu (Fe, Co, Ni, Mn ), uye magirazi epasi asingawanzo.
Magneto optical crystal
Magneto optic makristasi zvinhu zvekristaro zvine magneto optic mhedzisiro. Iyo magneto-optical effect yakanyatsoenderana nemagnetism yezvinhu zvekristaro, kunyanya simba remagineti yezvinhu. Naizvozvo, zvimwe zvakanakisa magineti zvinhu zvinowanzo magneto-optical zvinhu zvine yakanakisa magneto-optical zvimiro, senge yttrium iron garnet uye isingawanzo pasi iron garnet makristasi. Kazhinji kutaura, makristasi ane zvirinani magineti-optical zvivakwa ari ferromagnetic uye ferrimagnetic makristasi, akadai seEuO neEuS ari ferromagnets, yttrium iron garnet uye bismuth doped isingawanzo simbi yepasi garnet iri ferrimagnets. Parizvino, marudzi maviri aya emakristasi anonyanya kushandiswa, kunyanya ferrous magnetic crystals.
Kashoma pasi simbi garnet magneto-optical zvinhu
1. Mamiriro ezvinhu epasi isingawanzo simbi garnet magneto-optical zvinhu
Garnet mhando ferrite zvinhu rudzi rutsva rwemagineti zvinhu zvakakurumidza kugadzirwa munguva dzazvino. Chinonyanya kukosha pazviri irare earth iron garnet (inozivikanwawo semagnetic garnet), inowanzonzi RE3Fe2Fe3O12 (inogona kupfupikiswa seRE3Fe5O12), uko RE iri yttrium ion (mamwe anotorwawo neCa, Bi plasma), Fe. ions muFe2 inogona kutsiviwa neIn, Se, Cr plasma, uye Fe ions muFe inogona kutsiviwa neA, Ga plasma. Kune marudzi gumi nerimwe emhando imwe chete isingawanzo simbi yesimbi yakagadzirwa kusvika pari zvino, ine yakanyanya kufanana Y3Fe5O12, yakadimburirwa seYIG.
2. Yttrium iron garnet magneto-optical material
Yttrium iron garnet (YIG) yakatanga kuwanikwa neBell Corporation muna 1956 sekristaro imwechete ine yakasimba magneto-optical effects. Magnetized yttrium iron garnet (YIG) ine magineti kurasikirwa mirairo yakati wandei yehukuru yakaderera kupfuura chero imwe ferrite muyakanyanya-yakakwirira frequency ndima, ichiita kuti ishandiswe zvakanyanya sechinhu chekuchengetedza ruzivo.
3. High Doped Bi Series Rare Earth Iron Garnet Magneto Optical Materials
Nekuvandudzwa kwe tekinoroji yekutaurirana tekinoroji, zvinodiwa zvemhando yekufambiswa kweruzivo uye kugona zvakawedzerawo. Kubva pakuona kwekutsvagisa kwezvinhu, zvinodikanwa kuvandudza mashandiro emagneto-optical zvinhu semusimboti wezvitsaura, kuitira kuti kutenderera kwavo kweFaraday kuve nediki tembiricha coefficient uye yakakura wavelength kugadzikana, kuitira kuvandudza kugadzikana kwekuzviparadzanisa nemudziyo. tembiricha uye wavelength kuchinja. Yakakwira doped Bi ion yakatevedzana isingawanzo pasi simbi garnet makristasi matete uye mafirimu matete ave chinangwa chekutsvaga.
Bi3Fe5O12 (BiG) imwe crystal yakaonda firimu inounza tariro yekuvandudzwa kweyakasanganiswa magineti optical isolator. Muna 1988, T Kouda et al. yakawana Bi3FesO12 (BiIG) single crystal matete mafirimu kekutanga uchishandisa reactive plasma sputtering deposition method RIBS (reaction lon bhinzi sputtering). Zvadaro, United States, Japan, France, nevamwe vakabudirira kuwana Bi3Fe5O12 uye yakakwirira Bi doped rare pasi iron garnet magneto-optical mafirimu vachishandisa nzira dzakasiyana-siyana.
4. Ce doped zvisingawanzo pasi simbi garnet magneto-optical zvinhu
Zvichienzaniswa nezvinhu zvinowanzo shandiswa zvakadai seYIG neGdBiIG, Ce doped rare earth iron garnet (Ce: YIG) ine maitiro ehombe yeFaraday rotation angle, yakaderera tembiricha coefficient, yakaderera kunyura, uye yakaderera mutengo. Parizvino ndiyo inonyanya kuvimbisa mhando nyowani yeFaraday kutenderera magneto-optical zvinhu.
Kushandiswa kweRare Earth Magneto Optic Materials
Magneto optical crystal zvinhu zvine yakakosha yakachena Faraday mhedzisiro, yakaderera kunyura coefficient pawavelengths, uye yakakwirira magineti uye permeability. Inonyanya kushandiswa mukugadzira optical isolators, optical non reciprocal components, magneto optical memory uye magneto optical modulators, fiber optic kutaurirana uye yakasanganiswa optical zvishandiso, kuchengetedza komputa, logic kushanda uye kutapurirana mabasa, magneto optical kuratidza, magneto optical kurekodha, mitsva microwave zvishandiso. , laser gyroscopes, nezvimwewo Nekuramba kuchiwanikwa kwemagneto-optical crystal zvinhu, huwandu hwe midziyo inogona kushandiswa uye kugadzirwa ichawedzerawo.
(1) Optical isolator
Mune optical masisitimu akadai sefiber optic kutaurirana, kune mwenje unodzokera kune laser sosi nekuda kwekutaridzika kwenzvimbo dzeakasiyana zvikamu munzira yemaziso. Chiedza ichi chinoita kuti chiedza chekubuda kwelaser sosi isagadzikane, zvichikonzera ruzha rwemaziso, uye kudzikisira zvakanyanya simba rekutapurirana uye kureba kwekutaurirana kwemasaini mufiber optic kutaurirana, zvichiita kuti optical system isagadzikane mukushanda. An optical isolator ndeye passive optical mudziyo unongobvumira unidirectional mwenje kuti upfuure, uye iyo inoshanda musimboti yakavakirwa pakusadzokororwa kweFaraday kutenderera. Chiedza chinoratidzwa kuburikidza nefiber optic echoes chinogona kunyatsotsaurwa nemaoptical isolator.
(2) Magneto optic current tester
Kukurumidza kusimukira kweindasitiri yemazuva ano kwakaisa pamberi pepamusoro zvinodiwa zvekutapurirana uye kuona magidhi emagetsi, uye echinyakare high-voltage uye yakakwirira ikozvino yekuyera nzira dzichasangana nematambudziko akakura. Nekuvandudzwa kwefiber optic tekinoroji uye sainzi yezvinhu, magneto-optical current testers vakawana kutariswa kwakapararira nekuda kwesimba ravo rekudzivirira uye anti-kupindira, kuyera kwechiyero, nyore miniaturization, uye hapana njodzi dzinogona kuputika.
(3) Microwave mudziyo
YIG ine hunhu hweakatetepa ferromagnetic resonance mutsara, dense chimiro, yakanaka kugadzikana tembiricha, uye idiki diki hunhu kurasikirwa kwemagetsi pakukwira kwepamusoro. Aya maitiro anoita kuti ive yakakodzera kugadzira microwave michina yakasiyana-siyana yakadai se-high-frequency synthesizer, bandpass filters, oscillator, AD tuning drivers, nezvimwewo. Yakashandiswa zvakanyanya mu microwave frequency band pasi pe X-ray band. Pamusoro pezvo, magineti-optical makristasi anogona zvakare kugadzirwa kuita magneto-optical zvishandiso senge ring-shaped zvishandiso uye magineti-optical kuratidza.
(4) Magneto optical memory
Muhunyanzvi hwekugadzirisa ruzivo, magneto-optical media inoshandiswa kurekodha uye kuchengetedza ruzivo. Magneto optical chengetedzo ndiye mutungamiri mukuchengeterwa kwemaziso, ane hunhu hwehukuru hwakakura uye mahara swapping yekuchengetedza yemaziso, pamwe nemabhenefiti ekudzimeka kunyorazve kwemagineti ekuchengetedza uye avhareji yekumhanya yekumhanya yakafanana nemagineti hard drive. Iyo mutengo wekuita reshiyo ichave kiyi yekuti magneto optical disks inogona kutungamira nzira.
(5) TG imwe kristaro
TGG ikristaro yakagadzirwa neFujian Fujing Technology Co., Ltd. (CASTECH) muna 2008. Zvayakanakira zvikuru: TGG single crystal ine yakakura magneto-optical constant, high thermal conductivity, low optical kurasikirwa, uye high laser damage threshold, uye inoshandiswa zvakanyanya mukuwedzera kwemazinga akawanda, mhete, uye mbeu jekiseni lasers seYAG uye T-doped sapphire.
