Abstract:
The magnetocaloric properties of the systems exhibiting magnetic (paramagnetism (PM)–ferromagnetism (FM)) and structural (hexagonal lattice–orthorhombic lattice) transitions separated (overlapped) in temperature are analyzed in terms of a model of interacting parameters of magnetic and structural orders. It is shown that the magnetocaloric characteristics of the system can increase or decrease during overlapping of the structural (P63/mmc – Pnma) and magnetic (PM–FM) transitions in the dependence of the character of combination of the low-symmetric orthorhombic (Pnma) and high-symmetric hexagonal (P63/mmc) phases with a ferromagnetic order.
