Dielectric and magnetic properties of fe and ti based perovskite oxides

Abstract

The present PhD thesis deals with extensive investigation of magnetic and dielectric properties of 1 YFe1 xMnxO3 x 0 to 0 3 2 Bi1 xSmxFeO3 x 0 to 0 3 3 PbTi1 xFexO3 x 0 to 0 3 and 4 BaTi1 xFexO3 x 0 to 0 3 samples Study of complex impedance spectra dielectric constant and ac electrical conductivity of YFe1 xMnxO3 x 0 8220 0 3 compounds elucidates the role played by both grains and grain boundaries in shaping the dielectric relaxation The relaxation is attributed t
