On the magnetocaloric effect in Gd(Zn_(1-x)Cd_x)

摘要

In this work, we calculate the magnetocaloric effect in the compounds Gd(Zn_(1-x)Cd_x). We use a model Hamiltonian of interacting spins in which the indirect exchange interaction parameter between localized spins was calculated as a function of Cd concentration. The calculated isothermal entropy changes and the adiabatic temperature changes upon magnetic field variations are in good agreement with the available experimental data.
