“…The calculated R, CPE and a parameters are summarized in Table 3. It is clear that the resistance values decrease with the increase of temperature, which can be explained by the increased mobility of the charge carriers that contribute to the conduction process [52]. The resistance at these temperature values can be deduced from the well-defined impedance peak, which was found to follow the Arrhenius relation:…”

“…Each composition has a semicircle to confirm the electrical conductivity due to contribution of grains and grains boundaries [54]. The strength of relaxation and frequency range is the cause for the formation of semicircle [55]. Increasing the concentration of Sn increases the radius of semicircle and enhances its peak sharpness.…”

The structural, magnetic, dielectric, and surface morphology of BiSn x Fe 1-x O 3 (x = 0.0 to 1.0) was analyzed experimentally. The samples were synthesized by a simple chemical micro-emulsion method. The X-ray diffraction (XRD) analysis reveals structural distortion at A site and B site of BFO due to Sn doping in rhombohedral phase. The EDX data certify Sn is well incorporated in BiFeO 3 . The effect of Sn doping on crystal size and grain size has also been addressed. The FTIR analysis elaborates absorption at 555 cm −1 which is due to stretching and bending vibrations of O-Fe-O bonds. The magnetic properties are illustrated by vibrating sample magnetometer (VSM). The magnetic moments and exchange mechanism described theoretically by DFT analysis which support the experimental results. The dielectric behavior of studied materials has been evaluated by dielectric constant (ɛʹ), tangent loss (tanδ), real and imaginary part of impedance, and Cole-Cole plots in 1-3 GHz. The spin-orientated magnetism and dielectric response increase their potential for microwave absorber and sensor.Keywords Room temperature ferromagnetism • Micro-emulsion method • Vibrating sample magnetometer * Q.
