Abstract:In this paper we theoretically discuss the magnetocaloric effect in Tb5Si2Ge2 under applied pressure. We use a model of interacting spins where the effective exchange interaction parameter was self-consistently calculated in terms of the electronic structure of the compound. Our theoretically calculated isothermal entropy changes show the good trend of the available experimental data.
Keywords:Magnetocaloric effect  Spin Hamiltonians  Rare earth compounds
