dc.descriptionWe studied the magnetization as a function of temperature and magnetic field in the compounds Nd0.5Sr0.5MnO3, Nd0.5Ca0.5MnO3, Sm0.5Ca0.5MnO3, Dy0.5Ca0.5MnO3, and Ho0.5Ca0.5MnO3. Ferromagnetic, antiferromagnetic, and charge ordering transition in our samples agreed with previous reports. We also did specific-heat measurements with applied magnetic fields between 0 and 9 T and temperatures between 2 and 30 K in all five samples. Below 10 K the specific-heat measurements evidenced a Schottky-like anomaly for all samples. However, we could not successfully fit the curves to either a two level or a distribution of two-level-Schottky anomaly.
