Abstract
Structural, magnetic and ferroelectric properties of 0.6BaTiO3–0.4(Ni0.5Zn0.5Fe2O4) multiferroic nanocomposite are presented here. The structural properties of the samples were studied by XRD and Raman spectroscopy which confirm the formation of BaTiO3 (BTO) phase with a tetragonal perovskite structure and a small secondary spinel phase due to the ferrite content. The magnetic and electric orderings were investigated by vibrating sample magnetometer (VSM) and ferroelectric (P–E) loop tracer at room temperature. The inception of ferroelectric properties is due to barium titanate. The remnant polarization increases ∼5 times for the composite with Ni0.5Zn0.5Fe2O4 (NZFO) substitution compared to BTO. The remnant polarization is conducive for switching applications of multiferroic composite.
