Metallic ferromagnetism in a single-band model. II. Finite-temperature magnetic
properties

Physical Review B 40, 9061 (1989)

A recently proposed band model to describe metallic ferromagnetism is studied at finite temperatures within the
mean-field approximation. We discuss in particular the behavior of critical temperature, specific heat, magnetic
susceptibility above Tc, and magnetization below Tc assuming a constant density of states. The model overcomes in
a simple way the major difficulties of Stoner theory and yields properties that are consistent with a variety of observations
in ferromagnetic metals and alloys.
