摘要：

The present study reports the new functionality of room temperature ferromagnetism (RTFM) in non-magnetic Cadmium (Cd) doped BaTiO3 nanostructures, contrary to pure diamagnetic BaTiO3. TEM images show that grain size reduces with Cd doping. XPS analysis indicates that cation vacancies induce RTFM in Cd doped BaTiO3. Magnetic study reveals that pure BaTiO3 exhibits diamagnetic like signature, while Cd doped BaTiO3 show ferromagnetic feature with saturation magnetization (Ms & SIM; 9.70x10-3 emu/g), remanent magnetization (Mr & SIM; 0.22x10-3 emu/g) and coercive field (Hc & SIM; 42.54 Oe), respectively. The current investigation also indicates that the induced RTFM could meet the demand of developing spintronic applications.
