Abstract :
Heat capacity of the perovskite NdGaO3 has been measured in the range of 0.15 K<T<3 K showing an anomaly that is interpreted as ordering of the Nd3+ ions at Tc=0.97±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
