Abstract
Pr-Fe co-doped SrTiO3 films are prepared by the metal organic deposition method on (111) Pt/Ti/SiO2/Si substrates. Their dielectric and electric modulus behaviors are investigated in the temperature range of 30-500 °C with different measuring frequency of 102â¼106 Hz. A typical ferroelectric relaxation phase transition is shown and its location shifts to the low temperature with the increase of Fe content. The imaginary parts of electric modulus Mâ³ exhibits the variable relaxation process with different Fe content, which is relation with OVs, PNRs and phase transition, and the possible causes of relaxation behavior dependence are analyzed in detail.
