Abstract

Based on the spin w aves theory of ferromagnets and interaction quantum theory betw een the spin w ave and microw ave radiation，this paper discusses magnetization of the ferromagnetic ultrafine particle in the low temperature case and absoption of microw ave by system of magnon，w hich contains quantum size effects．

Keywords：ferromgnetic ultrafine particle；magnetization；absorbent function；quantum size effect
