Ba₅CaTi_2-xFe_xNb₈O₃₀ (x = 0.00, 0.02, 0.04, 0.06 and 0.08) Tungsten Bronze Ceramics were synthesized by conventional solid-state method. In this paper, the effect of Fe substitution in BCTN (Barium Calcium Titanium Niobate) on micro-structural, Raman, ferroelectric and ferromagnetic properties are discussed. The X-ray diffraction (XRD) result reveals the formation of a single-phase tetragonal structure of the synthesized samples. The grain size and morphology of the sample were confirmed by using a Scanning electron microscope (SEM). The P–E loop exhibits the ferroelectric nature of TB ceramics. The substitution of Fe ions improves the magnetic behavior of synthesized material.
