| Abstract: Electroceramics with ferropiezoelectric and ferri-ferromagnetic properties have been studied. These ceramics consist of two phases, a ferroelectric one (commercial BaTiO3) and a ferromagnetic one (MFe2O4, with M = Ni, Zn. Co, obtained through co-precipitation methods), which are later mixed using mechanical milling. A characterization of the previous phases is made by means of electronic microscopy and X-ray diffraction. The results of the magnetic, electric, ferroelectric and piezoelectrical response of the different compound compositions are obtained. The coexistence of phases is made clear, with a greater magnetic response in the samples of ferrite with Co and a greater piezoelectric in the samples of ferrite with Ni. These results are analysed, and the potential of the use of different mixtures is discussed. (c) 2007 Elsevier Ltd. All rights reserved. | |
