“…The characteristic accords remarkably well with results shown in earlier works. 29) In addition, it is worth to note that the twist angle could further increase with a higher H c than 1300 A/m, as shown in Fig. 5(b).…”

Fe 83 Ga 17) 99.4 B 0.6 wires with 0.5 mm diameter were prepared by hot forging, rolling and combining hot and cold drawing. Strong ©110ª fiber texture was obtained in the as-drawn and annealed wires by alternating current with short time. Compared with the fracture elongation of about 0.1% in the as-drawn wire, the property increased to 16.1% in the annealed wire. The Young's modulus of annealed wire was up to 174.3 GPa. In the annealed wires, the maximum twist angle of 206AA/cm and magnetostriction ¦ of ¹48 ppm was achieved respectively. The obvious voltage signals of the torsional wave could be detected up to 400°C in the annealed wire, which was attributed to the high Curie temperature and highly thermal-stable magnetic properties of the FeGa alloy. The linear downward trend of the velocity of the torsional wave was observed from room temperature to around 250°C. The results indicate that (Fe 83 Ga 17) 99.4 B 0.6 wire is suitable for the high-temperature waveguide device.

“…5 Li et al have found that magnetostriction of the waveguide wire is an important factor for the Wiedemann effect, and that the Wiedemann torsion increases with magnetostriction. 6 The signal amplitude of Fe-Ga waveguide wire displacement sensor is higher than that of Fe-Ni waveguide wire displacement sensor. 7 In the previous work, the output voltage model of magnetostrictive displacement sensor under the action of spiral magnetic field was established.…”

“…In fact, the Wiedemann twist angle produced by the waveguide wire is related to the magnetostriction of the waveguide wire. 6,9 Therefore, it is interesting to investigate the relationship between the output voltage of magnetostrictive displacement sensor and the magnetostriction of the waveguide.…”

Structural design and output characteristic analysis of magnetostrictive tactile sensor for robotic applications AIP Advances 8, 056622 (2018) Based on the Wiedemann effect and inverse magnetostritive effect, the output voltage model of a magnetostrictive displacement sensor has been established. The output voltage of the magnetostrictive displacement sensor is calculated in different magnetic fields. It is found that the calculating result is in an agreement with the experimental one. The theoretical and experimental results show that the output voltage of the displacement sensor is linearly related to the magnetostrictive differences, (λ l -λ t ), of waveguide wires. The measured output voltages for Fe-Ga and Fe-Ni wire sensors are 51.5mV and 36.5mV, respectively, and the output voltage of Fe-Ga wire sensor is obviously higher than that of Fe-Ni wire sensor under the same magnetic field. The model can be used to predict the output voltage of the sensor and to provide guidance for the optimization design of the sensor. © 2017 Author(s).

This paper presents the first measurement of ring-shaped Galfenol’s high frequency-dependent minor flux density loops. The frequencies of applied AC magnetic field are 1k, 5k, 10k, 50k, 100k, 200k, 300k, 500 kHz. The measurements show that the cycle area between the flux density and magnetic field curves increase with increasing frequency. High frequency-dependent characterization, including coercivity, specific power loss, residual induction, and maximum relative permeability are discussed. Minor loops for different max induction are also measured and discussed at the same frequency 100 kHz. Minor loops with the same max induction 0.05 T for different frequencies 50, 100, 200, 300, 400 kHz are measured and specific power loss are discussed.
