Highlights: ► The double P–E loops observed indicate that the BFMO film was aged. ► The double-loop feature fades away gradually with the increase of Zr content from 1 to 3 mol%. ► The deaging effect of Zr can be proved by testing the asymmetry of Ec and retention properties. -- Abstract: BiFe{sub 0.95−x}Mn{sub 0.05}Zr{sub x}O{sub 3} thin films were prepared on ITO/glass substrates using a sol–gel method. The P–E hysteresis loops before and after the high electric field treatment were measured to investigate the deaging effect of Zr{sup 4+} ions on BiFe{sub 0.95}Mn{sub 0.05}O{sub 3} thin films. It was found that the BiFe{sub 0.95}Mn{sub 0.05}O{sub 3} thin film shows typical double P–E hysteresis loops before the cycling of high electric field, indicating that the film was aged. The double-loop feature fades away gradually with the increase of zirconium doping content from 1 to 3 mol%, demonstrating that Zr{sup 4+} ions indeed have deaging effect on the aged BiFe{sub 0.95}Mn{sub 0.05}O{sub 3} film. Such deaging effect of Zr{sup 4+} ions can be further proved by comparing the asymmetry of the coercive field before and after the cycling of high electric field as well as the charge retaining capability.
