Abstract

Abstract Basic information about magnetocaloric effect (MCE) in ferromagnetic solids is expounded in brief. An overview of experimental data on MCE in shape memory alloys is presented with the emphasis on the giant MCE observed in the materials exhibiting magnetostructural phase transformations. The Landau-type theory of such phase transformations is used for the quantitative description of giant MCE and heat capacity of shape memory alloys. The difference between this approach to a theoretical description of giant MCE and the orthodox thermodynamic theory of MCE is discussed.
