Giant magnetocaloric and barocaloric effects in Mn(As1-xSbx)

In this work, we discuss the magnetocaloric and barocaloric effects in the doped compound Mn(As1-xSbx). by using a model based in the framework of the band theory In this model, the two body interaction is treated in the Hartree-Fock approach and the chemical disorder is treated in the coherent potential approximation. Our theoretically calculated magnetocalonc potentials are in very good agreement with the available experimental data Besides, our theoretical calculations show that the doped compound Mn(As1-xSbx) also exhibits giant barocalonc effect.
