Abstract
In this communication, structural, microstructural and low magnetic field influenced dielectric and impedance have been investigated for low cost chemically grown Bi0·85La0·15FeO3 thin film grown on FTO glass substrate by using sol–gel spin coating method. X–ray diffraction (XRD) reveals the successful growth of Bi0·85La0·15FeO3 film on FTO substrate. Surface morphology of the film has been examined by scanning probe method. Magnetoelectric (ME) properties of the film have been understood at room temperature. Magnetic field influenced dielectric behavior has been systematically investigated in the frequency range of 20 Hz to 2 MHz. The magnetic field induced alterations in the dielectric constant and impedance behavior at different frequencies confirm the complex nature of ME coupling between spin and lattice of BLFO film. Magnetic field dependent conductivity behaviors show a complex governance of charge carrier movements by the lattice disorder effect and spin alignment of iron ions in the BLFO lattice.
