Samarium Cobalt Magnets (SmCo Magnet)
Mafotokozedwe Akatundu
Maginito a Samarium-Cobalt (SmCo) ali ndi kutentha kwabwino kwambiri kwa Br (-0,035%/℃) kumapereka kulowetsedwa kwapamwamba kopezeka pamwamba pa 150 ℃ kutentha kogwira ntchito.Ngakhale ndi mtengo wokwera kuposa zida zina zamaginito, SmCo imapereka kuphatikiza kwakukulu kwamphamvu, kukhazikika kwamafuta, komanso kukana dzimbiri.Zovala zodzitchinjiriza nthawi zambiri sizimafunika kupatula ntchito zina.Koma SmCo ndiyopepuka komanso yofooka: mukayiponya, imasweka.
