Optical fiber current sensors are widely used in the online monitoring of a new generation power system because of their high electrical insulation, wide dynamic range, and strong anti-electromagnetic interference ability. Current sensors, based on fiber Bragg grating (FBG) and giant magnetostrictive material, have the advantages of high reliability of FBG and high magnetostrictive coefficient of giant magnetostrictive material, which can meet the monitoring requirements of digital power systems. However, giant magnetostrictive materials are expensive, fragile, and difficult to mold, so giant magnetostrictive composite materials have replaced giant magnetostrictive materials as the sensitive elements of sensors. High sensitivity, high precision, wide working range, low response time, and low-cost optical fiber current sensors based on magnetostrictive composites have become a research hotspot. In this paper, the working principle of the sensor, the structure of the sensor, and the improvement of magnetostrictive composite materials are mainly discussed. At the same time, this paper points out improvements for the sensor.

“…Therefore, in the past decades, much efforts have been paid on developing a R x Pr 1−x Fe 2 anisotropic compensation system by selecting another RFe 2 alloy with different signs of magnetocrystalline anisotropy constant K 1 to PrFe 2 to obtain large magnetostriction at low magnetic fields. [9][10][11][12][13][14][15][16][17] To develop a R x Pr 1−x Fe 2 anisotropic compensation system, the studies of crystal structures and spin reorientation temperature (T SR ) in PrFe 2 are significant. This is because for RFe 2 alloys, there is a one-to-one relationship between lattice distortion and EMD (rhombohedral structure with EMD along ⟨111⟩, orthorhombic structure with EMD along ⟨110⟩, and tetragonal structure with EMD along ⟨100⟩, respectively).…”

“…Low magnetocrystalline anisotropy frequently occurs at T SR . [9][10][11][12][13][14][15][16] Therefore, it is of great interest if we find a method to control it for different temperature applications. According to the investigations of Ga substitution for Fe in TbFe 2 system, the EMD of the compound may deviate slightly from the major axis of symmetry, and it leads to the increase of tetragonal distortion λ 100 .…”

The magnetostriction, magnetization, and spin reorientation properties in Pr(Ga x Fe1 – x )1.9 alloys have been investigated by high-precision x-ray diffraction (XRD) step scanning, magnetization, and Mössbauer spectra measurements. Ga substitution reduces the magnetostriction (λ ||) with magnetic field H ≥ 8 kOe (1 Oe = 1.33322 × 102 Pa), but it also increases the λ || value when H ≤ 8 kOe at 5 K. Spin-reorientations (SR) are observed in all the alloys investigated, as determined by the step scanned XRD, Mössbauer spectra, and the abnormal temperature dependence of magnetization. An increase of the spin reorientation temperature (T SR) due to Ga substitution is found in the phase diagram, which is different from the decrease one in many R(Tx Fe1 – x )1.9 (T = Co, Al, Mn) alloys. The present work provides a method to control the easy magnetization direction (EMD) or T SR for developing an anisotropic compensation system.
