“…The external magnetic field can also modify the permeability by changing the deflection of moments. The principle of this new MI sensor described here seems similar to those proposed in the past [1] [2], but the transmission effect is very different from the resonance. By selecting dimensional parameters, dielectric constant and etc., the characteristic impedance of the magnetic microstrip line should be designed to match the system impedance to be connected with it.…”

The microwave can be modulated by external fields that caused the impedance change due to the permeability variation in the magnetic strip. The amplitude variation of the microwave carrier was rectified to obtain output signals. A simple structure sensor has been developed that exhibited a high sensitivity of 10 mY/Oe, a high changing ratio of 48% in the transmission-line impedance and a broad signal bandwidth of 300 MHz. This sensor has great advantages of high sensitivity and broad bandwidth over MI sensors previously proposed.

“…A considerable interest has been focused on the giant magneto-impedance, GMI, effect in the amorphous soft ferromagnetic materials because of their important applications in highly sensitive micromagnetic sensors [1][2][3]. The GMI effect can be defined as the change of the impedance of a soft magnetic element carrying a high frequency current as a function of the external dc magnetic field.…”

PACS 75.50.KjThe magnetoimpedance effect has been measured in as-received and current annealed Fe 71 Cr 7 Si 9 B 13 amorphous wires under torsional stress varied up to 1.2 rad/cm. It was found that the torsional stress dependence of impedance of as-received amorphous wire has a non-monotonous shape with first an increase of the impedance and then a decrease. On the other hand, the impedance of current annealed wire directly starts to decrease with increasing torsional stress. The current annealing of wire results in a large variation in the magnitude of torsional stress impedance effect, (∆Z/Z) ξ (%), up to 150%. Also, a simple mathematical model based on the magnetic moment rotation to explain torsional stress versus impedance data was developed and the results were partly discussed on the basis of this model.

“…Although the effect has been found in amorphous alloys of different geometries (wire, ribbon, nanowire and film) the amorphous wire stands out among the GMI system due to magnetic softness and favorable geometry. The very large sensitivity of GMI on low magnetic field, stress and thermal treatment makes this effect very promising for technological applications [6][7] . It is generally understood that the combined effect of electromagnetic screening and magnetization dynamics in a ferromagnetic conductor leads to the GMI effect [8][9][10] .…”
