Structural, Dielectric And Magnetic Properties Of ZnFe2O4-Na0.5Bi0.5TiO3 Multiferroic Composites
AIP Conference Proceedings(2018)
摘要
Multiferroic xNa(0.5)Bi(0.5)TiO(3)-(1-x)ZnFe2O4 (x=0.10, 0.20) composites were prepared by conventional solid state reaction method. Rietveld analysis of XRD data shows that samples exhibit both cubic (Fd-3m) and rhombohedral (R3c) crystal structure. Structural parameters and unit cell volume of samples vary with composition. The dielectric constant and dielectric loss (tan delta) display dispersion at low frequency due to space charge polarization and inhomogeneity in the composites. Magnetic analysis depicts the antiferromagnetic behavior of composites and magnetization is enhanced with the introduction of ferrite (ZnFe2O4) phase.
