Structural, dielectric, and conductivity studies of strontium-doped Gd2NiMnO6 perovskite

Valence band spectra and doping based alterations in band gap and electric modulus of Nd2NiMnO6

“…The doping at A-site of double perovskites R 2 NiMnO 6 (R = rare-earth) has been carried out by many researchers and this kind of doping has been found to modify the various physical properties of these perovskites for potential applications [30][31][32]. Keeping in view enhanced applications of such type of double perovskites by doping, we have analyzed the electrical characteristics, by carrying out the electric modulus study of all the three samples as a function of frequency and temperature so as to see the electrical behavior of samples with changing frequency and temperature.…”

Investigation of the structural, dielectric, magnetic properties and NTC-thermistor response of CaBiFeMnO6 double perovskites

“…The relative dielectric constant term, which represents polarisation, describes the ability of the asprepared material to preserve energy. 28,29 The dissipation factor, or tan d = e 00 /e 0 , is obtained by the correlation between the imaginary and real parts of the complex dielectric function. The dissipation term is calculated as e 00 = e 0 + tan d. The electric field induced by an electric current has a phase variation that is indicated by the symbol d. 29,30…”
