Features of Formation of the Magnetocaloric Phenomena in [Mn.sub.1 - t][Ti.sub.t]As and [Mn.sub.1 - x][Cr.sub.x]NiGe Systems

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 or...

Description
Summary: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 ([P6.sub.3]/mmc-[P.sub.nma]) and magnetic (PM-FM) transitions in the dependence of the character of combination of the low-symmetric orthorhombic ([P.sub.nma]) and high-symmetric hexagonal ([P6.sub.3]/mmc) phases with a ferromagnetic order.
