Abstract

The effects of pressure on the antiferromagnetic long-range ordering in Pr2CuO4-y have been studied between 0.25 and 0.75 GPa by neutron diffraction experiments at temperatures down to 12K. Under a pressure of 0.25 GPa, successive magnetic phase transitions are observed at TN ≈ 250 K and T1 ≈ 170 K, as was reported previously. Upon further cooling in the present experiments another transition has been found at T2 ≈ 50 K. These magnetic phase transitions can be attributed to spin reorientations induced under high pressure. The temperature T1 increases at a rate of about 40 K/GPa with pressure; on the other hand, T2 decreases greatly at - 120 K/Gpa.
