Study of magnetic and specific heat measurements at low temperatures in Nd0.5Sr0.5MnO3, Nd0.5Ca0.5MnO3

Abstract The magnetization at low temperatures for Nd 0.5 Sr 0.5 MnO 3 and Nd 0.5 Ca 0.5 MnO 3 samples showed a rapid increase with decreasing temperatures, contrary to a La 0.5 Ca 0.5 MnO 3 sample. Specific heat measurement at low temperatures showed a Schottky-like anomaly for the first two samples. However, there is no a straight forward correlation between the intrinsic magnetic moment of the Nd 3+ ions and the Schottky-like anomaly.
