Resumen
The synthesis and magnetoelectric characterization of multiferroic Bi 5 Ti 3 FeO 15 is presented. Samples were obtained by the molten-salts method. Structural analysis was performed by means of electron microscopy and x-ray diffraction. The increase of plate-like crystallites' dimensions with increasing reaction temperature is characterized. Magnetoelectric parameters are measured under a pulsed magnetic field of 2 · 10 4 Oe amplitude. Textured polycrystalline ceramics are property cut and electrically polarized. Longitudinal and transversal magnetoelectric voltages are sensed, from liquid-nitrogen to room temperatures. Only low-temperature transverse magnetoelectric effect is observed as significant.
