Dielectric, magnetic and multiferroic characterization of nanocomposites based on spinel and perovskite ferrites and barium titanate

Abstract

This study explores the synthesis, charactertzation, and multiferroic property evaluation of nanocomposites based on spinel and perovskite ferrites combined with barium titanate. The research involves synthesizing and ana|yzing zinc-doped nickel ferrite (Nir-*Zn*FezO+), zinc-doped cobalt ferrite (Co,-Zn*FezO+), and strontium-substituted bismuth ferrite (Bir-*Sr*FeO:) using XRD, SEM, EDAX, LCR meter, and VSM. Photocatalytic studies were conducted using methylene blue degradation. The work further investigates multiferroic composites of these ferrites with BaTiOs in different weight ratios, analyzingtheir structural, dielectric, magnetic, and ferroelectric behavior. The findings highlight their potential in multifunctional applications, with conclusions and future research directions outlined
