Magnetoelectric properties of multiferroic aurivillius type Bi7Fe3Ti3O21 ceramics
2020
Multiferroic Bi7Fe3Ti3O21 ceramic materials having six perovskite-like layers
were prepared by solid state reaction from simple oxides and sintered at
1263K. The microstructure and magnetoelectric properties were investigated.
Based on dielectric measurements, the value of magnetoelectric coupling
coefficient was figured. The magnetization as a function of temperature and
magnetic field at selected temperatures was examined. Additionally, the
hysteresis loop at 2 K was measured. The molar concentration of magnetic
ions Fe3+ in the multiferroic Bi7Fe3Ti3O21 compound was also determined.
