Abstract

Description

Magnetic properties of the Co valence tautomers are considered in wide range of magnetic field and temperature. Particularly, a model of the first order structural phase transition accompanied by a magnetic moment jump is proposed. The phase diagrams of the phase transition on a B-T plane (B is magnetic field and T is temperature) are calculated for four ligand types. Dependence of the critical magnetic field on physical characteristics known from experiments (transition temperature at the absense of magnetic field, entropy change per formula unit, energy difference between two phases) is found. The phase diagram is parametrized for comparison with other phase transitions of this kind.
