摘要：

Amorphous Heisenberg ferromagnets are discussed within the framework of an inhomogeneous mean field approximation in the limit of small amorphicity. In this limit Curie temperatures, susceptibility and magnetization can be expressed in terms of the pair correlation function fo the amorphous system. The results are compared with previous mean field theories. It is shown that the usual bond model is valid only for zero temperature.
