Mubihe byashize, icyiciro cya 30 cyangwa 32 nicyo cyiciro cyo hejuru cya Samarium Cobalt abantu hafi ya bose bo mu Bushinwa SmCo batanga magnet bashoboraga gutanga. Icyiciro cya 35 Samarium Cobalt yiganjemo amasosiyete amwe yo muri Amerika, nka Arnold (Arnold Magnetic Technologies, icyiciro cya RECOMA 35E), EEC (Electron Energy Corporation, 34C SmCo). Horizon Magnetics nimwe mumasosiyete make ya magneti ashobora gutanga urwego rwa 35 rukuruzi ya SmCo mubwinshi hamwe na Br> 11.7 kGs, (BH) max> 33 MGOe na Hcb> 10.8 kOe.
1. Imbaraga nyinshi ariko uburemere buke. Kuri Samarium Cobalt, iki cyiciro cyongerera ingufu ubwinshi bwingufu kugirango zihuze na progaramu zimwe zikomeye aho ingano ntoya no kunoza imikorere aribyo byihutirwa
2. Umutekano muke. Kuri iki cyiciro, BHmax, Hc na Br birarenze ibyiciro byambere bya magneti ya Sm2Co17 nkicyiciro cya 32, kandi ubushyuhe bwubushyuhe hamwe nubushyuhe bukabije bwakazi buba bwiza.

. Isi idasanzwe Dy (Dysprosium) na Tb (Terbium) ifite ububiko buke mubihugu bigarukira ariko birakenewe kumasoko maremare ya Neodymium yo mu rwego rwo hejuru harimo urwego AH, EH cyangwa na UH, inyinshi murizo zikoreshwa mumoteri menshi yamashanyarazi. 2011 habaye izamuka ryibisazi ryibikoresho fatizoigiciro cyisi kidasanzwe. Iyo igiciro kidasanzwe cyisi kizamutse, icyiciro cya 35 cya Samarium Cobalt, cyangwa nicyiciro cya 30 gishobora kuba ibikoresho byiza bya magneti kubakoresha gukoresha magneti kugirango bakomeze kuba igiciro gihamye ugereranije nabanywanyi babo. Bitewe nubushyuhe buhebuje, BHmax yo mu cyiciro cya 35 Samarium Cobalt iba nziza kuruta N42EH cyangwa N38AH ya magneti ya Neodymium ku bushyuhe burenga dogere 150C, ibyo bikaba bishobora kugaragara muriImirongo ya Hystereze.
