Abstract

In this paper we theoretically discuss the rotating magnetocaloric effect in HoAl2 single crystal. In order to do that, we use a model Hamiltonian of interacting magnetic moments including a term to account for the crystal electric field. Our theoretical calculations of the entropy changes are in a reasonable agreement with the available experimental data. Moreover, we predict the existence of an anomalous rotating magnetocaloric effect for some directions of the magnetic field rotation.
