Anomalies induced by calcium doping in NdCeCuO system
Abstract
Ca doping into either the superconducting samples Nd 1.85-xCe 0.15Ca xCuO y or the nonsuperconducting samples Nd 2-xCa xCuO y, leads to a sharp peak at about 200 K in their S(T) curves, and some structural anomaly is observed by variable-temperature x-ray diffraction at the corresponding temperature.
