Abstract

The results of the study of the coercivity of three-layer magnetic films obtained by chemical deposition are presented. The features of its changes from the thickness of the forming layers are determined. They are associated with the specificity of the magnetization reversal of the studied system, caused by a small difference in the values of the coercivity of the magnetic layers. The energy of the demagnetizing field is calculated, since an expression for the critical field for the magnetization reversal of the film is obtained, which describes well the experimentally observed linear dependence of the coercivity on the thickness of the magnetic layers.
