Abstract:

The relative stability of ferro- and antiferromagnetic state in 3d transition metals is investigated on the basis of itinerant model, that is, the Stoner model for ferromagnetic staes and the gap equation model for antiferromagnetic states. The realistic energy band structures are taken into account and the effective exchange interaction is introduced as only one parameter in the present paper. The theoretical predictions are in good agreement with the observed magnetic diagrams at absolute zero temperature. For example, it is quite reasonable in this model that bcc Fe is ferromagnetic, but bcc Fe is antiferromagnetic. It must be emphasized that there is no need to change the value of effective exchange interaction through all 3d elements to reproduce the observed magnetic moment of them.
