Abstract: CdWO₄ nanoflakes and nanorods have been successfully prepared through a mild template-free sonochemical method without any surfactants. The as-prepared samples were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). It was found that the ultrasound irradiation played an important role in the formation of CdWO₄ crystals. The results showed that CdWO₄ nanoflakes were first formed at the early stage, and CdWO₄ nanoflakes were transformed into nanorods as the ultrasonic time was prolonged from 0.5h to 1.5h.

Abstract: Fe-doped Na_0.5Bi_0.5TiO₃ was successfully synthesized by a hydrothermal method. Magnetic loops measured at room temperature indicate that the magnetism of NBT crystals can be controlled by Fe doping concentration. The magnetism of the Fe-doped Na_0.5Bi_0.5TiO₃ crystals develops from diamagnetism to ferromagnetism on increasing Fe doping concentration from 0 to 60mol %. The results presented in this study may provide an approach to widely exploring more multiferroic materials.
