Samarium CobaltMagnetNānā a me nā kikoʻī:

Ua kapa ʻia ʻo Samarium Cobalt (SmCo) magnet. ʻO kona kūpaʻa kiʻekiʻe i ka demagnetization a me ke kūpaʻa wela maikaʻi loa e hana ai ʻo SmCo kiʻekiʻe wela magnet a i ʻole Sm2Co17 magnet e hana paʻa ma lalo o ka wela kiʻekiʻe a hiki i 350 ° C. ʻO ka maʻamau, ʻaʻole pono ka uhi. No laila ʻo SmCo magnet kahi koho maikaʻi loa o nā mea magnet no nā noi hana kiʻekiʻe e like me ka aerospace, motorsports a me nā ʻoihana automotive.
