“…9 have Cr contents from 3 to 9.5 at.% and Fe contents of 26 to 36.5 at.%, and satisfy the required magnetostriction of over 20×10 -6 . These trends are in relative accord with the studies of Klokholm, (Klokholm and Aboaf, 19811 8), and Berger, (Berger, 19651 9). According to Berger, magnetostriction of Fe-Ni alloys is a function of the number of electrons/atom.…”

Magnetostrictive materials of the Fe-Ni-Cr ternary system for sensitivity enhancement of force sensors were searched by using a combinatorial method. Magnetostrictive materials for force sensors require large magnetostriction, high relative permeability, and high resistivity. This research is an attempt to find composition ranges that satisfy the following requirements: magnetostriction greater than 20×10 -6 , relative permeability greater than 4,000, and resistivity over 90 μΩ cm. A novel combinatorial deposition method, known as Combinatorial New Facing Targets Sputtering (Combi-NFTS) method was applied to fabricate libraries of samples with various compositions. Samples for measurement of the relative permeability and resistivity were synthesized with a composition distribution by using Combi-NFTS onto a 108 mm×76 mm glass substrate. After deposition of thin film, each sample is divided into 10 mm×10 mm. The relative permeability and resistivity were measured by using a vibrating sample magnetometer and the four probe method, respectively. Bilayer cantilever samples for evaluation of magnetostriction were fabricated onto a 6 mm×20 mm×0.1 mm Si substrate, whereby deflection of the samples changes when a magnetic field is applied. The laser lever method was used to measure the cantilever deflection. The results indicate that the composition range with an Fe content of 26-36.5 at.%, a Ni content of 61-66 at.%, and a Cr content of 7.5-9.5 at.% satisfy the requirement criteria.

“…GMR (and GMI) sensors too have been extensively tested for measuring a variety of mechanical quantities, for instance contact-free position [53], angle and speed [54], stress (in steel bars, [55]) and torque [56]. They appear also useful for non-destructive testing [57] and, because of their small size, for biomedical applications; see for instance Refs [58] and [59].…”

“…When the elastic wave arrives at the position of the coil, the magnetic domains under the coil would be changed and magnetic flux intensity B would also be changed with the reverse magnetostrictive effect. Based on the Faraday law of electromagnetic induction, the faradism voltage e would be detected in coil, which expressed as in (1) [5][6][7].…”

The magnetostrictive position sensor is a kind of displacement sensor utilizing the magnetostrictive effect and inverse effect of magnetostrictive material. This essay discussed the influence of the fixed end of the sensor system on the detected signal with the driver impulse. The fixed end waves (a kind of elastic wave) were described and defined in this essay. The mechanisms of torsional magnetic field on the long magnetostrictive material line and fixed end waves were discussed, and relative theory models were constructed in this paper. Experiments showed that the fixed end wave of the system could be generated and transmit along the line with impulse current, which is also a kind of noise wave should be removed or weakened. Consequently, this essay should provide the theory basis and data for promoting the signal quality of the signal detection of the sensor.
