It is sometimes difficult to draw the line separating ferromagnetic from paramagnetic substances. 嚴格區別鐵磁性與順磁性物質(zhì)有時(shí)是很困難的。
It is the critical point of the phase transition of ferromagtic or ferrimagnetic materials into paramagnetic materials. 是指磁性材料中自發(fā)磁化強度降到零時(shí)的溫度，是鐵磁性或亞鐵磁性物質(zhì)轉變成順磁性物質(zhì)的臨界點(diǎn)。
