Abstract:
In this study, the bulk ceramics with general formula La0.7Sr0.3Fe1-xNixO3; 0.0 ? x ? 0.2 nanocrystalline samples were successfully prepared by citrate autocombustion technique. The effect of Ni2+ ion substitution on the AC electrical conductivity and dielectric properties at different frequencies 400 KHz to 5MHz was studied. The obtained data reveal that ?/, and tan? increase as Ni2+ ion increases due to the increase the number of vacancies at the B site as Ni2+ content increases. The magneto-electric coefficient was measured for all nanomultiferroics samples and ferroelectric properties was examined for all prepared samples as well as and the data obtained that the higher value of magneto-electric coefficient at x=0.2.
