Magnetên Samarium Kobalt (SmCo Magnet)
Danasîna hilberê
Magnetayên Samarium-Kobalt (SmCo) xwedan hevrêziya germahiya Br ya herî baş e (-0,035% / ℃) ku li ser germahiya xebatê ya 150℃ înduksiyonek bêkêmasî ya berdest dide.Tevî lêçûnek ji materyalên din ên magnetîkî, SmCo berhevokek berbiçav a enerjiya bilind, aramiya termal, û berxwedana korozyonê peyda dike.Kincên parastinê bi gelemperî ji bilî serîlêdanên taybetî ne hewce ne.Lê SmCo pir hişk û zirav e: heke hûn wê bavêjin, ew ê bişkîne.
