On the magnetocaloric effect of itinerant electron systems with first order transition

de Medeiros, L.G.; de Oliveira, N.A.; von Ranke, P.J.; … - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 6, pp. 1355-1360

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...
