Abstract

The influence of combined application of external hydrostatic pressure and a magnetic field parallel to the c-axis on the magnetic phases in UNi₂Si₂ was studied by measuring electrical-resistivity anomalies related to magnetic phase transitions. As a result, the pressure evolution of the B-T magnetic phase diagram is presented. Both the magnetic field and the pressure promote the ground-state uncompensated antiferromagnetic phase at the expense of the AF-I phase, which exists at higher temperatures. The value of the critical field for suppression of the AF-I phase becomes considerably reduced with increasing pressure. The applicability of the mean-field approach within the axial Ising model for explaining pressure effects on magnetic phase transitions is discussed.
