Synthesis, Structural and Dielectric Properties of Pure and Ni Substituted Bismuth Ferrite

Article Preview

Abstract:

Multiferroics have been known as materials exhibiting both ferroelectric and ferromagnetic properties in same phase, they have interesting physical properties as well as possibility of practical application in some new memories, spintronics and sensor devices. The present work reports the fabrication of pure and Nickel substituted Bismuth Ferrite by simple hydrothermal method at 180 o C for 11 hours. The structural study was carried out using X-ray powder diffraction (XRD), and the Dielectric properties were investigated over a wide range of frequency and temperature. The image of SEM is in good agreement with the XRD analysis. The synthesis method is simple and cost effective. KEYWORDS: Multiferroics; Dielectric loss; Hydrothermal method; XRD.
