Dhulka Dhulka |Samarium(SM)
Sanadkii 1879, ayuu Bossbaudku wuxuu ogaadey in Elens Dhul adag oo ku yaal Neouyymumium 'prsoidmium nerdoymium "oo laga helay niobium ytrium ytrium your, oo loo magacaabay Samaarium engegle, sida magaca loo yaqaan' ore '.
Samaarium waa midab hurdi khafiif ah oo waa sheyga ceyriinka ah ee lagu samaynta magist-ka joogtada ah ee samatal-ka ku-saleysan. Samaarium Cobatt Magtem-ga Magtem-ka ayaa ahaa kuwa ugu horeeya magnet magnet-ka ee loo adeegsado warshadaha. Noocan magnet joogta ah wuxuu leeyahay laba nooc: taxanaha SMCO5 iyo taxanaha SM20CO17. Horraantii 1970-yadii, taxanaha SMC5 ayaa la sameeyay, xilli dambe, taxanaha SM2CO17 ayaa la sameeyay. Hadda waa baahida loo qabo kan dambe kaasoo ah diiradda ugu weyn. Daahirsanaanta Samaarinium Oxide ee loo adeegsado Samaarium Cobalt magthers uma baahna inuu aad u sarreeyo. Marka laga eego aragtida qiimaha, qiyaastii 95% badeecada ayaa inta badan la isticmaalaa. Intaas waxaa sii dheer, Samaarinium Oxide waxaa sidoo kale loo isticmaalaa sinada dhoobada dhoobada iyo daloolka. Intaas waxaa sii dheer, Samarium sidoo kale wuxuu leeyahay guryaha nukliyeerka, kaas oo loo isticmaali karo maadaama agabyada qaab dhismeedka, aaladda gaashaandhigga iyo xakameynta qalabka tamarta atomikada, taasoo ka dhigeysa in qashin-qubka nukliyeerka ah in si badbaado leh loo isticmaalo.
