Abstract

The problem of metallic ferromagnetism has been an outstanding problem for solid-state theorists [1], In recent years large progress has been made in understanding of the problem from the viewpoint of spin fluctuations [2]. It still seems to us, however, no definite answer has been given to the question what is essential for the appearance of ferromagnetism. For instance, although the single-band Hubbard model has been employed by many investigators, it is not known whether the model can be ferromagnetic or not. Therefore it still has some meaning to study this simplest model in detail and to examine under which conditions it simulates a ferromagnet.
