IMPACT OF AMORPHIZATION ON CRITICAL TEMPERATURE OF FERROMAGNET
AbstractIn solid state physics, the issue of ferromagnetism and magnetism in general, in structured amorphous materials, attracted great interest in recent years, both in 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 configuration of magnetic atoms. In the computer experiments presented in this paper, the general-purpose software Maple was used, as well as a simplified Ising model, which implies that it is a ferromagnetic with a small impact of anti-ferromagnetic state. In this paper the effect of amorphization on critical temperature of ferromagnet is presented. The change of spontaneous magnetization depending on the temperature is observed, in a temperature range close to the critical temperature, and a critical temperature shift for different influences of nonhomogeneity of the interaction energy. The results are compared with results of other authors who deal with the same subject matter
