Phase transitions in magnetics with two compensation points induced by magnetic field directed perpendicular to the easy axes

Abstract In the mean field approximation, the field-induced phase transitions in Prussian blue analogs with two compensation points are theoretically investigated. It is established that in the region between compensation points, the type of H − T phase diagram is strongly dependent on chemical compound. The small change in chemical compound gives rise to the appearance (or disappearance) of collinear phase region.
