REMARKS ON THE OGUCHI TRANSFORMATION,

Abstract

It is shown that the Oguchi transformation in the theory of ferromagnetism is a low-temperature spin wave approximation, the validity of which depends on the implicit assumption that the kinematical interaction can be ignored. This limitation has the consequence that the theory of Oguchi and Honma, if accepted at higher tem peratures, predicts an infinite Curie tempera ture. (Author)
