Mu 1879, Boysbaudley yavumbuye ikintu gishya kidasanzwe mu isi muri "praseodymium neodymium" yakuwe mu bucukuzi bwa niobium yttrium, maze ayita samarium ukurikije izina ryaya mabuye.

Samarium ni ibara ry'umuhondo ryoroheje kandi ni ibikoresho fatizo byo gukora Samarium cobalt ishingiye kuri magnesi zihoraho.Magari ya Samarium cobalt niyo ya mbere ya magneti adasanzwe yakoreshejwe mu nganda.Ubu bwoko bwa rukuruzi ihoraho ifite ubwoko bubiri: Urukurikirane rwa SmCo5 na Sm2Co17.Mu ntangiriro ya za 70, havumbuwe urukurikirane rwa SmCo5, kandi mugihe cyakurikiyeho, urutonde rwa Sm2Co17 rwavumbuwe.Noneho icyifuzo cya nyuma nicyo cyibandwaho.Ubuziranenge bwa okiside ya samariyumu ikoreshwa muri samariyumu cobalt magnet ntabwo ikeneye kuba hejuru cyane.Urebye ibiciro, hafi 95% yibicuruzwa bikoreshwa cyane.Mubyongeyeho, okiside ya samariyumu ikoreshwa no mububiko bwa ceramic na catalizator.Byongeye kandi, samariyumu ifite kandi imiterere ya kirimbuzi, ishobora gukoreshwa nkibikoresho byubatswe, ibikoresho byo gukingira hamwe nibikoresho byo kugenzura ingufu za atome zitanga ingufu, bigatuma imyuka ya kirimbuzi itanga ingufu nini zo gukoreshwa neza.
