Abstract

The isothermal magnetic entropy change has been obtained for the bilayer system that consists of S_u and S_l valued spins in each layer. The relation between the IMEC and the spin value as well as the value of exchange interaction between two layers have been obtained. Recently experimentally given double peaks behavior for manganite bilayers has been demonstrated theoretically, and explanation is given. On the other hand, the conditions that give rise to transition from this double peak behavior to the single peak behavior have been obtained and discussed.
