In this paper we study the magnetocaloric effect in the Laves phase pseudobinary Er(Co 1 - c Ni c ) 2 . We use a theoretical model, considering both the localized spins of rare-earth ions and the itinerant electrons of the transition elements. The two-body interactions are treated in the mean-field approach and the disorder is treated in the coherent-potential approximation. The calculated isothermal magnetic entropy and the adiabatic temperature change exhibit a good agreement with the… Expand

TLDR
