STUDY OF STRUCTURAL, ELECTRICAL AND OPTICAL PROPERTIES OF Bi0.9La0.1Fe0.5Mn0.503 (BLFMO) NANOSTRUCTURED THIN FILM

Abstract

Multiferroic materials exhibits magnetoelectric coupling between magnetic and ferroelectric phase ordering. In the present work, the La and Mn co-doped BiFe03 (BFO) nanostructured thin films with various thicknesses were deposited on LaNi03 (LNO) coated Si substrate by pulsed laser deposition technique (PLD). The structural, electrical, and optical properties of BLFMOILNO/Si heterostructure thin films were systematically investigated. The asdeposited BLFMO thin films were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FE-SEM), Energy dispersive spectroscopy analysis (EDS), impedance analyzer, atomic force microscopy (AFM), and ferroelectric tester. The doping effect at A,B-site have been evaluated and found the improvement in the multiferroic properties of BLFMO thin films. Therefore, Variation in the thickness from 100 to 830nm had a significant impact on the properties of BLFMO thin films.
