      Structural, magnetic and ferroelectric properties of 0.6BaTiO$_3$–0.4(Ni$_{0.5}Zn$_{0.5}Fe$_2$O$_4$) multiferroic nanocomposite are presented here. The structural properties of the samples were studied by XRD and Raman spectroscopy which confirm the formation of BaTiO$_3$ (BTO) phase with a tetragonal perovskite structure and asmall 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 inceptionof ferroelectric properties is due to barium titanate. The remnant polarization increases ∼5 times for the composite with Ni$_{0.5}$Zn$_{0.5}$Fe$_2$O$_4$ (NZFO) substitution compared to BTO. The remnant polarization is conducive forswitching applications of multiferroic composite.
