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 ($P 6_3/mmc$ – $P_nma$) and magnetic (PM–FM) transitions in the dependence of the character of combination of the low-symmetric orthorhombic ($P_nma$) and high-symmetric hexagonal ($P 6_3/mmc$) phases with a ferromagnetic order.
