摘要：

Itinerant-Electron Metamagnetism (IEM) is characterized by a first-order transition occurring, under the effect of varying external parameters such as temperature, magnetic field or pressure, between a nonmagnetic or low-induced-moment state and a ferromagnetic large-moment state. It is usually ascribed to peculiar features in the band structure of the considered systems. A new approach is proposed in the present paper in which this phenomenon results simply from the interplay between the magnetic energy and the elastic energy.
