“…This effect takes place in mixed or compound materials that have ferro-piezoelectric and magnetoestrictive phases and results from the linking of both phases. The magnetoelectric effect in compound materials is analysed from the Van Suchetelene approach, as a result of the properties of each phase [15,16]. A suitable combination of the two phases must lead jointly to the coexistence of piezoelectric and piezomagnetic/ magnetostrictive phases.…”

Magnetoelectric composites were synthesized from piezoelectric BaTiO 3 and ferrimagnetic NiFe 2 O 4 . These two phases are mixed, mechanically milled and heat treated. A characterization is made by means of electronic microscopy and x-ray diffraction. The results of the magnetic, electric, ferroelectric and piezoelectrical response of two different compositions are obtained. The composites are superparamagnetic in all the measured temperature range. It was observe a magnetic change induced by a structural transition of the ferroelectric phase. The composites behaves as an acceptable mechanical resonator when the content of the ferroelectric phase is equal or greater than 60 wt.%.
