ResumoHeat capacity of the perovskite NdGaO/sub 3/ has been measured in the range of 0.15 K<T<3 K showing an anomaly that is interpreted as ordering of the Nd/sup 3+/ ions at T/sub c/=0.97/spl plusmn/0.01 K. This is, to our knowledge, the best example of a 3D XY magnetic ordering in a rare earth system, free from any other contribution, and the first such example of a Nd compound. >
