Description
The random magnetic anisotropy model with mixed temperature dependent exchange coupling is used to describe metamagnetic transitions in certain amorphous rare earth alloys. The Hamiltonian for these amorphous magnetic systems is derived. In order to see the antiferromagnetic to ferromagnetic metamagnetic transition the free energy in absence of an external magnetic field is calculated in dependence on absolute temperature. The critical temperature of the metamagnetic transition is the same for both the crystalline and the amorphous phases
