Model Hamiltonian

On the basis of Monte Carlo simulations, we investigate the temperature dependence of magnetization of Ni-Mn-Sb Heusler alloys, in which the part of the Mn atoms interact antiferromagnetically. It is shown that this antiferromagnetic exchange is responsible for existence of several magnetic phase transitions in the Heusler alloys. For a certain set of parameters of the model Hamiltonian we obtain coupled martensitic and magnetic phase transitions. Results of simulations agree in an excellent way with the experimental magnetization curves.

The magnetic properties of zigzag metallic chains have been calculated based on the Monte Carlo simulation. The reduced transition temperatures and the magnetization have been obtained for different exchange interactions and for different crystal fields. The hysteresis cycle is obtained for different exchange interactions, temperatures and crystal field. The superparamagnetic behavior is obtained for a specific value of temperatures and crystal field. The second-order phase transitions are also observed. The obtained results are comparable with some given by experiment results and theoretical calculations.
