The authors wish to thank J.R. Weir III for invaluable technical assistance in neutron diffraction under high pressure. The neutron diffraction experiments were carried out at the Oak Ridge National Laboratory under the U.S.-Japan Cooperative program on Neutron Scattering. The Oak Ridge National Laboratory is managed by Martin Marietta Energy Systems, Inc. for the Division of Materials Science of the U.S. Department of Energy under Contract No. DE-AC05-84OR21400.

N2 - 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.
