“…Field sensitivity values are also important in magnetic field sensor designs of samples with high MI variation. In the literature, the field sensitivity value for the as-received Co72.5Si12.5B15 wire was calculated as 0.22% per A/m [14]. In our study, S value was determined as approximately 1.35% per A/m in the negative magnetic field region as a result of the low-time annealed (Fig.…”

In this study, thermal treatments dependence of Magneto-impedance (MI) effect in Co72.5Si12.5B15 wires has been investigated. Wires were annealed at 460 °C for different times (1-400 min). It was found that low time annealed leads to increase in magnetic softness. The largest change in the MI was observed at 1 MHz frequency value. It was determined that maximum MI, coercivity (Hc) and maximum field sensitivity (S) values were 247%, 1.28 A/m and 1.35% per A/m respectively in the wire annealed at 460 °C for 10 minutes. This high MI and field sensitivity value occurring in low annealed time shows that this wire can be used in the design of low magnetic field sensors.

“…Effort has been made to minimize the noise associated with the signal since the amplitude of the second harmonic voltage was small. Details of the experimental arrangement were presented elsewhere [11]. The amplitude of the driving ac current (I ac ) and the frequency were 4 mA and 300 kHz, respectively.…”
