Popis:	The magnetocaloric effect for ferrimagnetic materials of the hexagonal system, for which a characteristic feature is the presence of spontaneous spin-orientational transitions when the temperature changes, is analyzed. Expressions are obtained for the field and temperature dependences of the magnetocaloric effect of singlecrystal and polycrystalline materials, taking into account higher-order magnetic crystallographic anisotropy constants. The results of the calculations agree well with experimental data on the magnetocaloric effect in polycrystalline grain-oriented samples of hexaferrites from the BaCo2−xZnx-W system.
