摘要：

LaBi4FeTi3O15 is a 4-layered ferroelectromagnetic material belonging to the Aurivillius' family of compounds having an orthorhombic distortion. 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 properties. The scanning electron micrographs of the samples showed differences in microstructures. Magnetization measurements were carried out from 80 K to room temperature and B-H loop traces indicated a small hysteresis around the origin. Dc magnetoelectric studies were performed and outputs of 2.52 mV/cm/Oe and 2.49 mV/cm/Oe respectively were obtained for the unixially and isostatically pressed samples.
