Copper Metaborate CuB2O4 Phase Diagrams Based on the Results of Measuring the Magnetic Moment

摘要

The magnetic phase transitions and the phase diagrams of the CuB2O4 multiferroic are studied. Phase diagrams of copper metaborate in a magnetic field directed along the [100] and [001] axes are plotted using the results of measuring the magnetic moment. Evidences for the existence of polycritical points are obtained.
