|Abstract:||Multiferroic BiFeO 3 (BFO) thin film exhibiting ferroelectric and enhanced magnetic properties was grown on La 0.67Sr 0.33MnO 3 (LSMO) buffered Pt/TiO 2/SiO 2/Si substrates by off-axis RFmagnetic sputtering, where a highly (111)-oriented texture was obtained. The BFO/LSMO thin film exhibits excellent ferroelectric and dielectric behavior (2Pr = 210.7 μC/cm2, 2Ec = 435 kV/cm, ε r = 116.8, and tanδ ∼ 2.7% at 1 kHz), together with a long fatigue endurance up to 10 10 switching cycles at amplitude of 300 kV/cm. An enhancement in magnetic behavior was also observed with Ms = 89.5 emu/cm 3, which is largely contributed from the magnetic layer of LSMO. The coexistence of ferroelectric and ferromagnetic properties in the double layered BFO/LSMO thin film makes it a promising candidate system for applications where the magnetoelectric behavior is required. © 2011 The Electrochemical Society.|
