摘要：
Polycrystalline ceramics of 1 - x[Na0.5Bi0.5TiO3] - x[BiFeO3](NBT-BFO) were synthesized by the modified Pechini's method to study their magnetic and magnetoelectric properties. A series of solid solutions exhibiting magnetoelectric output were formed when two iso-structural compounds Na0.5Bi0.5TiO3 (NBT) and BiFeO3 (BFO) were combined. Polarization-electric field hysteresis loops revealed that the maximum polarization (similar to 23 mu C/cm(2) for x = 0.1) decreased continuously with the increase of BFO content, following a hard doped effect. Piezoelectric charge coefficient (d(33)) = 41 pC/N was obtained for the ceramics with x = 0.1 and the value continues to decrease with the composition. Magnetic hysteresis loops represent the canted antiferromagnetic nature for x <= 0.6 and ferromagnetic-like behavior for the BFO-rich compositions. Magnetoelectric coupling was determined by measuring the magnetoelectric voltage coefficient which is similar to 12.4 mV/cm-Oe at an ac magnetic field of 10 Oe (1 kHz), for x = 0.1 sample.
