BiFeO3 doped-BNT-BT0.08 piezoelectric and magnetic nanowires, derived from sol–gel precursor
Source abstract
Abstract
Lead-free piezoelectric (Bi0.5Na0.5)0.92- Ba0.08TiO3, doped with 5 mol %BiFeO3 (BNT-BT- BFO) nanowires was prepared from its corresponding precursor sol. A polycarbonate membrane with the thickness of 30 lm and the pore diameter of 100 nm was used as template. Nanowires with average diam- eter of *80 nm and different lengths of a few microns were prepared from BNT-BT-BFO precursor sol with *0.03 M concentration. Ferroelectric and piezoelec- tric characterizations of BNT-BT-BFO nanowires were performed using AFM-PFM equipment. The HR-TEM micrograph of nanocrystals, SAED patterns, and XRD pattern indicated that BNT-BT-BFO nano- wires crystallized on the lattice of rhombohedral (Na0.5Bi0.5TiO3) phase. The BNT-BT-BFO nanowires showed a significant piezoelectric response, suggest- ing a good piezoelectric behavior. The saturation magnetization of the nanowires, measured at room temperature and at 5 kOe magnetic field, was Ms = 0.061 emu/g. A saturated ferromagnetic hys- teresis loop has been also obtained.
