摘要

THE magnetic property of the ultrafine particles differs from that of the bulk materials and has a lot of applications. Because of the size effect, magnetically ordered materials exhibit both superparamagnetism and collective magnetic excitation, andthe magnetic transition temperature changes in the ultrafine particles with respect to the bulk materials as well.
