| Abstract: | The complex permittivity ?* of ceramics of bismuth-lanthanum manganite Bi0.5La0.5MnO3 has been measured in ranges of temperatures T = 10–200 K and frequencies f = 102–106 Hz. Clearly pronounced regions of the non-Debye dielectric relaxation have been revealed at low temperatures (T < 90 K). To describe them, the possible mechanisms have been proposed and discussed. The temperature dependences of magnetization, the anomalous behavior of which can be associated with the phase transition from the paramagnetic phase into the ferromagnetic phase occurring at T ～ 40–80 K, have been measured in the temperature range T = 10–120 K. |
