摘要：

An automatic apparatus allows fast studies of magnetic annealing and thermal variations of coercive force and remanent magnetization in cobalt substituted γ-Fe2O3 particles for magnetic recording. Experimental results are interpreted with Néel's model of directional order. The model and results permit an understanding of the origin of surface anisotropy of surface cobalt doped particles. © 1990 IEEE
