摘要：
Bi0.9Ba0.1FeO3 (BBFO)/La2/3Sr1/3MnO3 (LSMO) heterostructures are fabricated on LaAlO3 (100) substrates by pulsed laser deposition. Giant remnant polarization value (similar to 85 mu C/cm(2)) and large saturated magnetization value (similar to 12.4 emu/cm(3)) for BBFO/LSMO heterostructures are demonstrated at room temperature. Mixed ferroelectric domain structures and low leakage current are observed and in favor of enhanced ferroelectric properties in the BBFO/LSMO heterostructures. The magnetic field-dependent magnetization measurements reveal the enhancement in the magnetic moment and improved magnetic hysteresis loop originating from the BBFO/LSMO interface. The heterostructure is proved to be effective in enhancing the ferroelectric and ferromagnetic performances in multiferroic BFO films at room temperature.
