“…Giant magneto-impedance (GMI) material, which offers several advantages over conventional magnetic material, including a high sensitivity of 500%/Oe, was used as the inductive sensing element. The GMI material provided a sensitive route to detect the subtle change of magnetic field (42,43). As shown in Fig.…”

“…However, the rate of decrease of anisotropy constant is faster than that of the saturation magnetization. For this reason, permeability enhances very fast around T c (the ferro/paramagnetic transition temperature of the sample) [33][34]. The initial permeability of ferrites depends on many factors such as reversible domain wall displacement, domain wall bulging as well as microstructural features viz., intragranular porosity, chemical composition, average grain size and the presence of second phase etc [35].…”

1-x , where x = 0.00, 0.02, 0.04, 0.06 and 0.08 were prepared by the double sintering ceramic technique. Real part of the initial permeability µ', Curie temperature T c , imaginary part of the initial permeability µ", relative quality factor (Q-factor) of the samples were elaborately discussed as a function of frequency and temperature with increase of Fe-deficiency during the heating and cooling cycles.The temperature dependence of the imaginary part of the complex permeability curves are very interesting to note that there is a peak value of µ" at particular temperature which corresponds to the T c because at this temperature the samples might be in complete spin disorder. This reflects that at T c , a ferrimagnetically ordered state over comes K B T and becomes comparable with µ 0 H where the loss becomes maximum. Results of heating and cooling cycles were found to be very close to each other. The small difference during heating and cooling process might arise due to the thermal hysteresis which is accumulated in this work. In our study, it was noticed that the resonant frequency and T c increases first with the increase in iron deficiency and decreases after it takes a maximum at x = 0.06.
