Abstract:
We present the results of a heat capacity study of Pb3Mn7O15 single crystals with approximately equal concentrations of Mn3+ and Mn4+ ions. In the temperature interval between 210 and 260 K, an excess heat capacity of nonmagnetic origin, most likely associated with the process of charge localization, has been observed. Also, three pronounced anomalies corresponding to the changes in a magnetic subsystem of the crystal have been observed in the temperature dependence of the heat capacity. A broad...     »
