| Annotation | The investigation results of the influence of non-magnetic matrix conducting properties on the magnetization process of magnetic nanogranular films are presented. Effective field in the films with conductive matrix influences the properties of the magnetic subsystem and facilitates the establishment of magnetic correlation in the ensemble of ferromagnetic granules. Polarization of the electron subsystem leads to the appearance of the exchange interaction between magnetic moments of the nearest magnetic granules. One can state about initiation of indirect exchange interaction in the case when the field of indirect exchange will exceed the value of local magnetostatic fields. |
