Peculiarities of temperature behavior of magnetization in Co/Ge/Co films

In Letter the results of experimental and theoretical investigations of magnetic properties in trilayer Co/Ge/Co films are represented. The temperature dependences of films, being two phases in respect of magnetism, are studied. Experimental results are explained in the frameworks of impurity model, when the hexagonal cobalt grains are considered as quasi-Ising particles distributed chaotically and dissolved within an isotropic matrix of cubic cobalt. The fields of magnetization rise on the T-H plane are determined.
