Evidence of Surface Biasing and Multiferroic Properties in Ferroelectric (BNT)-Ferrimagnetic (LFO) Nanocomposites
The lead-free composite (1-x)Bi0.5Na0.5TiO3-(x)LaFeO3 with chemical composition [x = 0.00, 0.02, 0.04, 0.06, 0.08 and 1.00] has been prepared via the double step solid-state reaction method. The X-ray diffraction (XRD) patterns of the composites indicate its crystalline nature and indexed with rhombohedral (R3c) and orthorhombic (Pbnm) crystal symmetries. The Rietveld refinement of XRD patterns has been used to estimate the various crystal structure parameters. The microstructure of the composites indicates the non-homogeneous distribution of grains with different sizes. The dispersive nature of the frequency dependent dielectric properties is observed in the present composites. The temperature-dependent dielectric constant of the composites exhibits the relaxor behavior. The ferroelectric and magnetic properties of the composites describe its multiferroic behavior. The dielectric, ferroelectric, and magnetic properties of the present composites have been correlated with the multiferroic behavior.
期刊介绍：
