Improvement of magnetic properties, suggesting the effectiveness of Li0.5Fe2.5O4 (LF) in lower concentration doped in BaTi0.9Zr0.1O3 (BTZr). The composites with a formula of (1-x)BaTi0.9Zr0.1O3 + (x) Li0.5Fe2.5O4 (x = 0.0, 0.05, 0.10 and 0.15) synthesized by conventional solid state reaction method at 1150 °C. X-ray diffraction (XRD) peaks are indexed to the crystal planes for tetragonal perovskite and spinel ferrite observed in the samples. SEM micrographs show dense microstructure resulting in increasing grain size with an increase in ferrite content. Stability of magnetic phase in the higher temperature range, enhancing the Curie temperature with increase in ferrite content.
