Impedance Spectroscopy Properties of Pr0.67A0.33MnO3 (A = Ba or Sr) Perovskites
We have investigated the dielectric properties of Pr 0.67 Ba 0.33 MnO 3 (PBMO) and Pr 0.67 Sr 0.33 MnO 3 (PSMO) perovskites synthesized by the solid-state reaction method at 1473 K. Samples were characterized by complex impedance spectroscopy (CIS) in the frequency range from 40 Hz to 1 MHz, at room...
