Abstract: In this article, we investigate the influence of the first-order ferromagnetic-paramagnetic phase transition, on the magnetocaloric effect, under the combined effect of external magnetic field, pressure and magnetoelastic deformation. An application is made to Gd-5(SixGe1-x)(4), for x = 0.43 and 0.5. The obtained result leads to a good theoretical adjustment of the experimental data for isothermal magnetic entropy change.
