In this manuscript, iron based double perovskite oxides Ca2Fe1-xNixNbO6(x=0, 0.1) were successfully synthesized adopting the physical mixed oxide route and high temperature annealing. The influence of Ni substitution on the structure, band gap tuning, leakage current, dielectric, energy storage and magnetic properties of the parent ceramic is also discussed. A relatively high remnant polarization of 11.8 µC/cm2 with a reduced band gap of 1.9 eV is noticed in the Ni modified ceramic. It is found that the saturation magnetization increases from 0.359 emug−1 to 0. 892 emug−1 whereas the leakage current density decreases from 6.869E−6 to 5.52E-6 A/mm2 upon Ni substitution. The enhanced saturation magnetization and ferroelectric properties of the modified ceramic with lesser leakage current increases their energy storage capacity. The energy storage efficiency of the Ni substituted material increases from 15.52% to 71% with a reduction of hysteresis loss. Hence the increase in remnant polarization and decrease in band gap of the Ni modified ceramic aligns it toward ferroelectric photovoltaic application. |
