Dielectric, Magneto-Dielectric & Magnetic Properties of x[Co_0.9Ni_0.1Fe₂O₄]-(1-x)[0.5Ba_0.7Ca_0.3TiO₃-0.5BaZr_0.2Ti_0.8O₃] Multiferroic Composite

Abstract:

In the present work, we have synthesized x [Co_0.9Ni_0.1Fe₂O₄]-(1-x) [0.5Ba_0.7Ca_0.₃TiO₃-0.5BaZr₀_.2Ti_0.8O₃], x = 0.3, 0.4 & 0.5 multiferroic composite by hydroxide co-precipitation method. The structural and morphological analysis of the composite was carried out by using X-ray diffraction and Scanning Electron Microscopy. The XRD spectra confirm the perovskite phase and spinel phase. Dielectric properties of the composite were studied using Impedance analyzer. The variation of dielectric constant and loss of tangent (Quality factor) in the frequency range of 100 Hz to 1 MHz were investigated. Magnetocapacitance were measured for magnetic field up to 1 Tesla, which increases with increase in magnetic field. Dielectric constant possesses contribution due to magnetic field dependent interfacial polarization and variation due to induced stress which can be explained on the observed MD effect. Saturation magnetization of composites increases with increase in CNFO content.
