Abstract: In this paper we make a systematic discussion about the magnetocaloric effect of itinerant electron systems with first order transition. For this purpose, we use a microscopical model based in the framework of the band theory of magnetism, including the magnetoelastic interaction. Our calculations show that the magnetoelastic coupling parameter, which renormalizes the electron energy hopping, is responsible for the appearance of the first order transition, the thermal hysteresis and the difference among the values of magnetocaloric potentials, calculated in the heating and cooling processes of the system.
