Ntibisanzwe isi magneto ibikoresho byiza
Ibikoresho bya optique bya magneto bivuga amakuru ya optique ibikoresho bikora hamwe na magneto optique muri ultraviolet kuri bande ya infragre.Ntibisanzwe isi ya magneto optique ni ubwoko bushya bwibikoresho bya optique ibikoresho bishobora gukorwa mubikoresho bya optique hamwe nibikorwa bitandukanye ukoresheje imiterere ya optique ya magneto no guhuza no guhindura urumuri, amashanyarazi, na magnetism.Nka modulator, izigunga, izenguruka, guhinduranya magneto-optique, guhindagura, guhinduranya icyiciro, gutunganya amakuru ya optique, kwerekana, kwibuka, laser gyro bias indorerwamo, magnetometero, sensor ya magneto-optique, imashini zandika, ibyuma bifata amashusho, imashini imenyekanisha imiterere, disiki ya optique , optique ya optique, nibindi.
Inkomoko yisi idasanzwe Magneto Optics
Uwitekaisi idasanzweitanga umwanya wa magneti udakosowe bitewe na 4f ya elegitoronike ituzuye, niyo soko ya magnetism ikomeye;Muri icyo gihe, irashobora kandi kuganisha kuri electroni, niyo mpamvu itera umunezero mwinshi, biganisha ku ngaruka zikomeye za magneto.
Ibyuma bidasanzwe byubutaka ntibigaragaza imbaraga za magneto optique.Gusa mugihe ibintu bidasanzwe byisi byinjijwe mubikoresho bya optique nk'ikirahure, kristu ivanze, hamwe na firime ivanze, bizagira ingaruka zikomeye za magneto-optique yibintu bidasanzwe byisi.Ibikoresho bisanzwe bikoreshwa na magneto-optique nibintu byamatsinda yinzibacyuho nka (REBi) 3 (FeA) 5O12 garnet kristal (ibintu byuma nka A1, Ga, Sc, Ge, Muri), RETM ya firime amorphous (Fe, Co, Ni, Mn ), hamwe n'ibirahuri bidasanzwe by'isi.
Magneto optique
Magneto optique ya kristu ni ibikoresho bya kristu hamwe ningaruka za magneto.Ingaruka ya magneto-optique ifitanye isano rya bugufi na magnetisme yibikoresho bya kristu, cyane cyane imbaraga za magnetisation yibikoresho.Kubwibyo, ibikoresho byiza bya magnetiki ni ibikoresho bya magneto-optique bifite ibikoresho byiza bya magneto-optique, nka garnet ya yttrium na garnet yisi idasanzwe.Muri rusange, kristu ifite ibyiza bya magneto-optique ni kristu ya ferromagnetic na ferrimagnetic, nka EuO na EuS kuba ferromagnets, yttrium fer garnet na bismuth doped isi idasanzwe ibyuma bya ferrimagnets.Kugeza ubu, ubu bwoko bubiri bwa kristu bukoreshwa cyane cyane kristu ya ferrous ferrous.
Ntibisanzwe isi icyuma garnet magneto-optique
1. Ibiranga imiterere yubutaka budasanzwe garnet magneto-optique ibikoresho
Ubwoko bwa Garnet ibikoresho bya ferrite ni ubwoko bushya bwibikoresho bya magneti byateye imbere byihuse mugihe cya none.Icy'ingenzi muri byo ni garnet yisi idasanzwe (izwi kandi nka magnetiki garnet), bakunze kwita RE3Fe2Fe3O12 (ishobora kuvugwa mu magambo ahinnye yitwa RE3Fe5O12), aho RE ari ion ya yttrium (zimwe nazo zikaba zifatanije na Ca, Bi plasma), Fe ion muri Fe2 irashobora gusimburwa na In, Se, Cr plasma, na Fe ion muri Fe irashobora gusimburwa na A, Ga plasma.Hariho ubwoko 11 bwubwoko bumwe budasanzwe bwisi garnet yakozwe kugeza ubu, hamwe nibisanzwe ni Y3Fe5O12, mu magambo ahinnye yitwa YIG.
2. Yttrium icyuma garnet magneto-optique ibikoresho
Yttrium fer garnet (YIG) yavumbuwe bwa mbere na Bell Corporation mu 1956 nka kristu imwe ifite ingaruka zikomeye za magneto-optique.Magnetised yttrium fer garnet (YIG) ifite igihombo cya magneti itumiza ibintu byinshi byubunini munsi yizindi ferrite zose mumashanyarazi ya ultra-high frequency, bigatuma ikoreshwa cyane nkibikoresho byo kubika amakuru.
3. Byinshi Byinshi Byakurikiranye Bi Bidasanzwe Isi Icyuma Garnet Magneto Ibikoresho byiza
Hamwe niterambere ryikoranabuhanga ryitumanaho rya optique, ibisabwa muburyo bwo kohereza amakuru nubushobozi nabyo byiyongereye.Duhereye ku bushakashatsi bwibintu, birakenewe kunoza imikorere yibikoresho bya magneto-optique nkibyingenzi byigenga, kugirango kuzenguruka kwabo kwa Faraday bifite coefficient ntoya yubushyuhe hamwe nuburebure bunini bwumuraba, kugirango tunonosore ituze ryibikoresho byo kwigunga birwanya ubushyuhe n'uburebure bwumurongo.Byinshi cyane Bi ion ikurikirana isi idasanzwe icyuma garnet kristu imwe na firime yoroheje byahindutse intego yubushakashatsi.
Bi3Fe5O12 (BiG) firime imwe ya kristu yoroheje izana ibyiringiro byiterambere rya magneto optique yihariye.Muri 1988, T Kouda n'abandi.yabonye Bi3FesO12 (BiIG) firime imwe ya kristu yoroheje kunshuro yambere ukoresheje uburyo bwa plasma butera uburyo bwo kubika RIBS (reaction lon ibishyimbo).Nyuma yaho, Amerika, Ubuyapani, Ubufaransa, nabandi babonye neza Bi3Fe5O12 hamwe na Bi bihanitse bidasanzwe isi ya garnet magneto-optique ikoresheje uburyo butandukanye.
4. Ce yakoresheje isi idasanzwe ibyuma garnet magneto-optique ibikoresho
Ugereranije nibikoresho bisanzwe bikoreshwa nka YIG na GdBiIG, Ce doped yisi idasanzwe ya garnet yisi (Ce: YIG) ifite ibiranga inguni nini yo kuzunguruka ya Faraday, coeffisente yubushyuhe buke, kwinjiza bike, nigiciro gito.Nubu nubwoko bushya butanga ibyiringiro bya Faraday rotation magneto-optique ibikoresho.
Gukoresha Isi Ntibisanzwe Magneto Ibikoresho byiza
Magneto optique ya kristu yibikoresho bifite ingaruka nziza ya Faraday, coeffisente yo kwinjirira muke kumuraba wumuraba, hamwe na magnetisiyasi nini kandi byoroshye.Ahanini ikoreshwa mugukora ibikoresho bya optique, optique idasubiranamo, ububiko bwa magneto optique hamwe na moderi ya optique ya moderi, itumanaho rya fibre optique hamwe nibikoresho bya optique, ububiko bwa mudasobwa, ibikorwa bya logique nibikorwa byo kohereza, magneto optique yerekana, ibikoresho bya microwave bishya, ibikoresho bishya bya microwave , laser gyroscopes, nibindi. Hamwe nogukomeza kuvumbura ibikoresho bya magneto-optique ya kristu, urutonde rwibikoresho bishobora gukoreshwa no gukorwa nabyo biziyongera.
(1) Ibyiza byo kwigunga
Muri sisitemu ya optique nka fibre optique itumanaho, hari urumuri rugaruka kumasoko ya laser kubera kugaragara hejuru yibice bitandukanye muburyo bwiza.Uru rumuri rutuma urumuri rusohoka rwinshi rwisoko ya laser rudahungabana, rutera urusaku rwiza, kandi rugabanya cyane ubushobozi bwo kohereza hamwe nintera yitumanaho ryibimenyetso mubitumanaho bya fibre optique, bigatuma sisitemu ya optique idahungabana mubikorwa.Ihitamo rya optique ni igikoresho cyiza cya optique cyemerera gusa urumuri ruterekanijwe kunyuramo, kandi ihame ryarwo rikorwa rishingiye ku kudasubiranamo kwa Faraday.Umucyo ugaragazwa na fibre optique echo irashobora gutandukanywa neza na optique ya optique.
(2) Ikizamini cya Magneto optique
Iterambere ryihuse ryinganda zigezweho ryashyize ahagaragara ibisabwa byogukwirakwiza no gutahura amashanyarazi, kandi uburyo gakondo bwo gupima amashanyarazi menshi hamwe nuburyo bugezweho bwo gupima bizahura nibibazo bikomeye.Hamwe niterambere ryikoranabuhanga rya fibre optique hamwe nubumenyi bwibikoresho, ibizamini bya magneto-optique bigezweho byitabiriwe cyane bitewe nubushobozi bwabo bwiza bwo gukumira no kurwanya kwivanga, gupima neza, gupima miniaturizasi, kandi nta ngaruka zishobora guturika.
(3) Igikoresho cya Microwave
YIG ifite ibimenyetso biranga ferromagnetic resonance yumurongo, imiterere yubucucike, ubushyuhe bwiza butajegajega, hamwe nigihombo gito cyane kiranga electromagnetic gutakaza kumurongo mwinshi.Ibiranga bituma bikwiranye no gukora ibikoresho bitandukanye bya microwave nka synthesizeri yumurongo mwinshi, bande ya filteri, oscillator, AD tuning ya AD, nibindi byakoreshejwe cyane mumurongo wa microwave munsi yumurongo wa X-ray.Mubyongeyeho, kristu ya magneto-optique irashobora kandi gukorwa mubikoresho bya magneto-optique nkibikoresho bimeze nkimpeta na magneto-optique yerekana.
(4) Ububiko bwa Magneto optique
Muri tekinoroji yo gutunganya amakuru, itangazamakuru rya magneto-optique rikoreshwa mugufata amajwi no kubika amakuru.Ububiko bwa Magneto optique nubuyobozi mububiko bwa optique, hamwe nibiranga ubushobozi bunini no guhinduranya kubuntu kububiko bwa optique, hamwe nibyiza byo kongera guhanagura byongeye kubika ububiko bwa magneti hamwe numuvuduko ugereranije ugereranije na disiki zikomeye.Ikigereranyo cyibikorwa bizaba urufunguzo rwo kumenya niba disiki ya magneto optique ishobora kuyobora inzira.
(5) TG imwe rukumbi
TGG ni kristu yatunganijwe na Fujian Fujing Technology Co., Ltd. ikoreshwa cyane murwego rwinshi rwa amplification, impeta, hamwe nimbuto zatewe inshinge nka YAG na T-doped safiro
