“…This section compares the measurement results of several optical methods utilised to measure the high‐frequency strong magnetic field. As can be seen from Table 1, the measurement range of the proposed sensor composed of sensitivity enhancement structure, magnetostrictive nanoparticles, and epoxy resin matrix [79] is slightly lower than that of the sensor based on optical pumped magnetometer proposed by Kochukhov in 2020 [71]. And for the measurement of high‐frequency magnetic field, Bal used a single artificial atom to implement an ultrasensitive magnetometer [85].…”

Smart sensors with excellent performance are accelerating the development of biomedicine and the Internet of Energy. Nanodielectrics exhibit unique electrical and mechanical properties. As the predominant materials in optical magnetic field sensor (MFS), they can not only exert the anti‐interference of optical sensing, but improve the measuring characteristics of optical sensors. For instance, the optical fibre quantum probe for the magnetic field can obtain a higher sensitivity of 0.57 nT/Hz1/2, while the measurement range of the sensor that uses Co‐doped ZnO nanorods as cladding is 17–180 mT. Here, these exciting recent achievements in the realm of optical sensing methods for magnetic field detection are reviewed, with a focus on nanodielectrics, which provide an emerging opportunity to achieve higher sensitivity and a wider measurement range of MFS.

“…Under a magnetic field, this structure will concentrate the sensor’s stress, raising the sensor sensitivity to 0.983 pm/Oe. Zhang et al [ 84 ] also proposed a sensor with a similar structure, which enhanced the sensor sensitivity by 5.17 times. A research result in earlier years provided by Quintero et al [ 85 ] indicated that sensor sensitivity is impacted by the glues’ category and magneto-strictive powders’ density, and sensor sensitivity can be further improved by imposing some prestress.…”

The magnetic field is a vital physical quantity in nature that is closely related to human production life. Magnetic field sensors (namely magnetometers) have significant application value in scientific research, engineering applications, industrial productions, and so forth. Accompanied by the continuous development of magnetic materials and fiber-sensing technology, fiber sensors based on the Magneto-Refractive Effect (MRE) not only take advantage in compact structure, superior performance, and strong environmental adaptability but also further meet the requirement of the quasi-distributed/distributed magnetic field sensing; they manifest potential and great application value in space detection, marine environmental monitoring, etc. Consequently, the present and prevalent Magneto-Refractive Magnetic Field Fiber Sensors (MR-MFSs) are briefly summarized by this paper, proceeding from the perspective of physicochemical properties; design methods, basic performance and properties are introduced systematically as well. Furthermore, this paper also summarizes key fabrication techniques and future development trends of MR-MFSs, expecting to provide ideas and technical references for staff engaging in relevant research.
