Overview

abstract

• The magnetic behaviour of the Heusler alloys is modeled by an fcc Heisenberg system. The Hamiltonian includes effective magnetic couplings between first, second and third neighbor pairs. The ground state phase diagrams at zero magnetic field and their range of stability with regard to the interaction parameters are obtained using the method of linear inequalities. The Curie and Neel temperatures are calculated as a function of the interactions in the mean field approximation. The model is applied to describe the phase transitions occuring in the Pd2MnSbxIn1-x alloys. © 1994.
