摘要：

Motivated to improve the magnetic properties at high temperatures, we study the temperature dependence of the static response function of Heisenberg spins with different anisotropies on different lattices with and without the dipolar interaction. This inverse susceptibility can be interpreted as an effective;anisotropy constant. For cubic anisotropy it dies off much faster than the magnetization. Possible implication of this to the making of new high temperature soft magnetic materials is discussed. (C) 1998 Elsevier Science B.V. All rights reserved.
