Abstract
The theory of simultaneous magnetic and structural first-order transitions in crystals with strong cubic magnetic anisotropy is developed on the basis of a combination of the magnetic modified 8-state Potts model [1] and theoretical models of structural phase transitions in cubic crystals [2]. The magnetic heat capacity and specific volume, as well as the temperature dependence of the rhombohedron angle, are calculated in a wide temperature range. The calculation of the temperature evolution of high-temperature diffuse magnetic neutron scattering was performed. It was demonstrated that upon passing the Curie point the spectra characteristic of the diffuse scattering are transformed to the magnetic Bragg peaks.
