| Popis: | The samples of SrTiO3(STO) doped YFeO3(YFO) were prepared by solid-state reactions. The crystallographic structural analysis of the prepared samples has been studied. The phases of STO with cubic perovskite symmetry and YFO with tetragonal symmetry were formed. The intermediate samples have sustained the structural symmetry of YFO compound with expansion in the unit cell dimension. The effect of addition of STO on electric performance of YFO material has been investigated in this article. The complex permittivity usually becomes very high due to electrode polarization and carrier transport. Complex impedance, modulus studies indicated the presence of grains and grain boundary contribution, non-Debye type of relaxation of the doped ceramic samples. |
