Ubwino ndi kuipa kwa Sm2Co17 ndi SmCo5 okhazikika maginito zipangizo

Poyerekeza ndi SmCo5, ndiSm2Co17ili ndi zabwino izi:

1. The zili cobalt ndi samarium mu chilinganizo cha Sm2Co17 okhazikika maginito zakuthupi ndi otsika kuposa SmCo5 okhazikika maginito zakuthupi, amene kwambiri amapulumutsa mtengo wa zipangizo.Chifukwa samarium ndi cobalt zopangira ndi okwera mtengo osowa zitsulo, kotero mtengo wa Sm2Co17 okhazikika maginito chuma ndi wotsika kuposa SmCo5;

2. The maginito kupatsidwa ulemu koyenelera wa Sm2Co17 okhazikika maginito zakuthupi ndi za -0.02%/℃, akhoza ntchito mu osiyanasiyana -60 ~ 350 ℃, amene ndi wosayerekezeka SmCo5 okhazikika maginito zakuthupi;

3.Curie kutentha ndipamwamba.The Curie mfundo ya zinthu Sm2Co17 ndi za 840 ~ 870 ℃, ndi Curie mfundo ya zinthu SmCo5 ndi 750 ℃.Izi zikutanthauza kuti Sm2Co17 ndi kugonjetsedwa ndi kutentha kwambiri kuposa SmCo5.Komabe, poyerekeza ndi SmCo5 okhazikika maginito zakuthupi, kupanga ndondomeko ya Sm2Co17 ndi zovuta.Pofuna kukonza coercivity, iyenera kukhala yokalamba kwa nthawi zingapo, ndipo mtengo wa ndondomekoyi ndi wapamwamba kuposa wa SmCo5.Mu maginito okhazikika, Sm2Co17 maginito chuma ndi mtundu wa maginito okhazikika ndi kuthekera mkulu utumiki kutentha.

Chifukwa chakuchulukirachulukira kwa maginito okhazikika omwe amagwiritsidwa ntchito pamwamba pa 400 ℃ muzamlengalenga ndi mafakitale apamagetsi, zida zokhazikika zamaginito zokhala ndi kutentha kwakukulu kwautumiki komanso magwiridwe antchito abwino kwambiri zimalandiridwa ndi anthu.Ngakhale kutentha kwa ntchito ya Alnico maginito okhazikika kuli pamwamba pa 500 ℃, mphamvu yake yamkati ndiyotsika kwambiri kuti ikwaniritse zofunikira zogwiritsira ntchito.NdFeb osowa dziko lapansi okhazikika maginito thupi ali coercivity mkulu ndi zabwino mabuku ntchito, koma ntchito kutentha sangathe kukwaniritsa zofunika pamwamba, chifukwa cha otsika Curie kutentha ndi lalikulu coefficient kutentha.Chifukwa cha ntchito yake yabwino kwambiri, maginito a Sm2Co17 akhala akugwiritsidwa ntchito kwambiri mu galimoto, chida cholondola, chipangizo cha microwave, sensa, chojambulira ndi zina zamakono.
