Nd{sub 2}CuO{sub 4} is found to be a quasi-two-dimensional antiferromagnet with {ital T}{sub {ital N}}=255 K. Successive phase transitions occur due to the Cu{sup 2+} spin reorientation as well as, at low temperatures, the participation of the Nd{sup 3+} spins in the three-dimensional long-range order. A sharp peak corresponding to the two-dimensional spin correlations is observed in energy-integrated scans. The magnetic properties at high temperatures are closely similar to those in La{sub 2}CuO{sub 4}.
