摘要

The structure, ferroelectric and magnetic properties of (1 -x)BiFeO_3-Bi_(0.5)Na_(0.5)TiO_3 (x = 0.37) solid solution fabricated by a sol-gel method have been investigated. X-ray diffraction and Raman spectroscopy measurements show a single-phase perovskite structure with no impurities identified. Compared with pure BiFeO_3, the coexistence of ferroelectricity and ferrimagnetism have been observed at room temperature for the solution with remnant polarization P_r = 1.41 μC/cm~2 and remnant magnetization M_r - 0.054 emu/g.
