Magnetoelectric behavior in in situ grown piezoelectric and piezomagnetic composite-phase system

A few model combinations of piezoelectric (PE), perovskite and piezomagnetic (PM), spinel phase has been chosen on BaO–TiO–FeO–CoO quinary oxides system for in situ preparation of magnetoelectric composite materials by solid-state route. The various phases, which appeared during in situ preparation in different model systems, have been characterized by X-ray diffraction (XRD). The magnetoelectric effect (ME) of such composites has been measured by dynamic method. The present paper deals with a qualitative comprehension of the ME property of such composites in relation to their proposed composition model.
