Magnetocaloric effect in (GdxTb1-x)5Si4 by Monte Carlo simulations

In this work, we calculate the magnetocaloric effect in the series of compounds (GdxTb1-x)(5)Si-4. We use the classical Monte Carlo simulation to deal with the 4f spin-spin interaction as well as the disorder at the rare-earth sites. The calculated isothermal entropy change and the adiabatic temperature change upon variations of the magnetic field are in good agreement with the available experimental data.
