In this work we synthesized the multifunctional (La0.8Ca0.2)0.4Bi0.6FeO3 material using a sol-gel process. Structural and morphologic investigations reveal Pnma perovskite structure at room temperature with spherical polygonal nanoparticles. A detailed study of dependence dielectric electrical properties studied proves typical FE-PE transition colossal value real permittivity 350 K that allows use in energy storage devices. Thus, investigation frequency ac conductivity correlated barrier...
La1-2x Ba x Bi FeO3 (0.00 ≤ 0.20) nanoparticles were prepared by the auto-combustion method using glycine as a combustion fuel. X-ray diffractometry (XRD) measurements confirmed orthorhombic structure of synthesized compounds with Pnma space group principal majority phase and showed presence very minor secondary when > 0.1. The nanosize criterion was from crystallite size values calculated Williamson-Hall formalism. relaxation process has been studied frequency dependence imaginary parts...
In the present paper,
Bi0.8Ba0.1Er0.1Fe0.96Cr0.02Mn0.02O3 (BBEFCMO) multiferroic ceramic was synthesized through the sol-gel route. The impact of incorporating various dopants into both A and B sites BiFeO3 investigated, structural, Raman, dielectric, electric, magnetic properties were studied. X-ray diffraction analysis Raman spectroscopy revealed a rhombohedral structure with R3c space group for doped material (BBEFCMO). Dielectric examined across frequency range 102–106 Hz. present exhibits colossal dielectric...
