Abstract

The magnetic properties of the compound HoTiGe have been studied by means of magnetization measurements at different temperatures and fields. The results show that the material displays an antiferromagnetic-to-paramagnetic phase transition in low fields and a field-induced antiferromagnetic-to-ferromagnetic transition at higher field strengths. From the magnetization data, the magnetic sublattice exchange coupling constants n₁₁ and n₁₂ have been determined based on the two-sublattice model and the magnetic entropy change is calculated
