Impedance spectroscopy of dielectric properties of perovskite ceramics Bi(Mg1/2Ti1/2)O3
The dielectric properties of metastable high-pressure perovskite ceramics Bi(Mg 1/2 Ti 1/2 )O 3 were studied by impedance spectroscopy at frequencies of 25 Hz-1 MHz at various temperatures. It is established that, at temperatures higher than ∼450 K, the dc conductivity makes a significant contributi...
