Popis:	A Co valence tautomeric compound has been studied in a wide range of magnetic fields and temperatures. Magnetic susceptibility of the Co complex has been measured in explosive magnetic fields. An anomalous behaviour of the susceptibility curve at the field of 100 T was attributed to a field-induced phase transition. A model describing the phase transition was developed. Among the results of the model is a B – T phase diagram of the transition, where B is magnetic field and T is temperature. The obtained experimental results were analyzed in the framework of the proposed model and several important parameters have been estimated: value of the entropy change at the transition and energy difference between the two phases.
