抄録
<p>The BiFe1-xMnxO3(BFMO) film shows monoclinic structure distorted along the <110> direction, while high quality [CaFeO3(CFO)/BFMO] superlattice grows with tetragonal structure, lattice parameter of which in-plane is fit to that of Nb doped SrTiO3(001) substrate. The BFMO film and the [CFO/BFMO] superlattice show similar M-H curves and saturation magnetic moment as a function of temperature. Magnetic moment rapidly increases in low magnetic field region and then gradually develops and saturated in high field region at 10 K. At 300 K, magnetic moment saturates in low magnetic field. As a temperature increases, saturation magnetic moment per magnetic ion rapidly decreases above 10K, and then gradually reduces. The magnetic moment at 300K of BFMO is 0.107μB higher than 0.034μB detected in the [CFO/BFMO] superlattice, probably due to the thin BFMO layer in the superlattice. Estimated TC of the BFMO film and the superlattice is 600 K and 500K, much higher than room temperature. Leakage current behavior indicates the Fowler-Nordheim tunneling and Schottky emission at Au/BFMO interface and Poole-Frenkel hopping conduction in the BFMO layer.</p>
