Abstract: UCo2Si2 is an antiferromagnet below TN = 82.4 K. The magnetic ordering is accompanied by the pronounced anomalies of resistivity, which are very different for the current direction along the a- and c-axis. Evolution of the TN-related resistivity features with increasing hydrostatic pressure up to 7.3 GPa was studied in order to reveal the pressure effects on magnetism in UCo2Si2. The TN value is found to decrease with increasing pressure; the critical pressure of collapse of ordered magnetism is estimated as 7.8. GPa.
