Theoretical investigation on the magnetocaloric effect in the intermetallic Gd4Sb3Gd4Sb3

In this work, we use the Monte Carlo method to calculate the magnetocaloric effect in Gd4Sb3Gd4Sb3 compound, which has second order ferro-paramagnetic phase transition near room temperature. The theoretically calculated isothermal entropy change and the adiabatic temperature change upon magnetic field variations are in good agreement with the available experimental data.

►
► Gd4Sb3 exhibit a moderate magnetocaloric effect (MCE) around room temperature.
►
► We use the Monte Carlo method and mean field approach to calculate the MCE in Gd4Sb3.
►
► The results are in agreement with the available experimental data.
