MAGNETIC AND MAGNETOELECTRIC STUDIES IN POLYCRYSTALLINE LABI4FETI3O15

LaBi4FeTi3O15 is a 4-layered ferroelectromagnetic material belonging t o the Aurivillius' family of compounds having an orthorhombic distorti on. Polycrystalline samples of this compound were prepared by uniaxial pressing and cord isostatic pressing with a view to study the effect of different compaction techniques and its impact on the physical prop erties. The scanning electron micrographs of the samples showed differ ences in microstructures. Magnetization measurements were carried out from 80 K to room temperature and B-H loop traces indicated a small hy steresis around the origin. Dc magnetoelectric studies were performed and outputs of 2.52 mV/cm/Oe and 2.49 mV/cm/Oe respectively were obtai ned for the unixially and isostatically pressed samples.
