Point Defects in Ferromagnets

Abstract

Abstract A calculation is made of the local magnetization of the nearest neighbours of non‐magnetic impurities in a Heisenberg ferromagnet with spin quantum number equal to 1/2. For the higher temperatures below the Curie point a molecular‐field model is used. The results for the low‐temperature region, derived by method of the double‐time temperature‐dependent Green function, show that assumptions made in a previous study are valid.
