In solid state physics in recent years great interest attracted problem ferromagnetism and magnetism in general, in the structured amorphous materials, both in the theoretical and experimental research. It is known that the crystal and the amorphous structure of the same substance do not have the same characteristics. Amorphous magnets constitute a class of systems with the highest degree of disorder. The existence of ferromagnetism in amorphous materials is determined by the relation between exchange interactions and configurations of magnetic atoms. In the computer experiments presented in this paper, was used general-purpose software Maple and simplified Ising model, which implies that it is a ferromagnetic with small impact of anti ferromagnetic state. In this paper is presented effect of amorphization on critical temperature of ferromagnet. Considered the spontaneous magnetization changes depending on the temperature, in a temperature range close to the critical temperature and critical temperature shift for different effects of inhomogeneity energy interactions. The results are compared with results of other authors who deal with the same subject matter
