Rezumat

The temperature dependence of the spontaneous magnetization in rectangular ferromagnetic nanostructures is derived in the framework of a quantum microscopic approach taking into account discreetness of excitation spectrum. The results are discussed in connection to the existing phenomenological description of experimental data to suggest another general form of the temperature dependence of magnetization in nanostructures.
