| Abstract: | The appearance of ferroelectricity has been observed in magnetically ordered Co(Fe1?xTix)2O4 at room temperature. Magnetization and dielectric constant is found to increase with Ti doping. It is observed from an X-ray Photoemission Spectroscopy study that Ti goes to the octahedral site with (+4) ionic state. An M–H hysteresis curve at room temperature shows the ferrimagnetic ordering and a P–E loop at room temperature clearly indicates the existence of ferroelectricity. |
