Abstract

The effects of pressure on the antiferromagnetic long-range ordering in Pr₂CuO_4-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 T_N ≈ 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.
