Abstract
In this work, the impedance properties of Co68.15Fe4.35Si12.5B15 cobalt-based amorphous wires connected in a crossed configuration have been studied. For this purpose, at first, the magnetic properties of a single wire and also two wires perpendicular to each other were investigated. The obtained results for a single wire present a decrease and increase, respectively, in the transverse and longitudinal saturation magnetization by increasing the angle of the wire and the applied magnetic field. In the same time, the anisotropy field of a single wire shows the sinusoidal variations by increasing the angle from 0 to 90∘ whereas coercivity field has the lowest value at the angle of 45∘. Furthermore, the saturation magnetization and the coercivity of two crossed wires get the highest and lowest values at the angle of 45∘. Besides, the magneto-impedance and sensitivity of two crossed wires increase from 193 % and 4.95 (1/Oe) for an angle of 0∘ to 528 % and 20.05 (1/Oe) for an angle of 45∘, which is in agreement with the magnetic properties of wires. Altogether, our results show that crossed configuration of wires at an appropriate angle of magnetic field can improve the GMI response and make the samples more suitable for magnetic vector sensors.
