Abstract

(Pr,Mn)-codoped BiFeO₃ (BPFM) ultra-thin films of 85nm thickness were deposited on a SrRuO₃ (SRO)-coated (100) Nb-doped SrTiO ₃ substrate by pulsed laser deposition. Regardless of the SRO film thickness, the SRO and BPFM thin films showed perfectly (h00)-orientation on the substrate. On the other hand, the surface morphology and leakage current of the BPFM films strongly depended on the SRO film thickness. The BPFM ultra-thin film on a 115nm thick SRO electrode shows a hysteresis loop without any influences of leakage current. The remnant polarization 2P_r and the coercive voltage 2V_c at the maximum applied voltage of 10 V are 82 μ;C/cm² and 7.2 V, respectively.
