Special Issue Information
Dear Colleagues,
The global market for magnetic field sensors is expected to grow due to presence of a large automotive industry, demand for industrial control and automation, development of intelligent transport systems, and continuous growth of consumer electronics and other fields of applications. Moreover, new developments in advanced world-scale scientific experimental equipment, such as ITER Tokamak, Stellarator, free-electron lasers, electromagnetic launchers or high-field pulsed magnets require precise magnetic diagnostics in harsh environments. Therefore, the development of new magnetic sensor technologies with increased capabilities and wider ranges of operation is of great importance.
Despite the widespread use of Lorentz force-based magnetic sensors (Hall sensors), an increasing interest in magnetic sensors based on so-called magnetoresistive xMR (anisotropic AMR, tunneling TMR, giant GMR, and colossal CMR) effects suggests a possibility to integrate them with standard microelectronics technologies, such as CMOS chips, and to develop sensors systems with higher precision and lower dimensions of single components. Further, the other types of magnetic sensors, such as magneto-optic, magnetoimpedance or fluxgate sensors, are used in special industrial areas. Each application has specific requirements for the sensor fabrication technology, device specifications, magnetic field and temperature ranges of operation, and sensor accuracy.
Therefore, we invite the international community from academia and industry to present their recent developments by submitting papers for the Special Issue “Magnetic Sensors and Systems for Scientific and Industrial Applications”. Topics include but are not limited to:
- Magnetic materials, films, and structures and their technologies;

The commercialized magnetic field sensors are becoming one of the mostly important components in consumer, automotive, industrial and other areas of application. The decreased sensor’s dimensions keeping high sensitivity in a wide range of magnetic fields and temperatures for measurement of local magnetic fields or their spatial distribution are required in advanced scientific and industrial equipment. However, there is a lack of commercial sensors for measurements of high magnetic fields. Therefore, the search of advanced materials and engineering of their nanostructures exhibiting extraordinary properties or new phenomena for high magnetic field sensing applications is of great importance.
In this review, the main focus will be made on the investigations of thin films, nanostructures and two-dimensional (2D) materials exhibiting non-saturating magnetoresistance up to high magnetic fields. It will be demonstrated, how tuning of the nanostructure and chemical composition of thin ferromagnetic oxide films (such as manganites) could result in a remarkable colossal magnetoresistance up to megagauss. Such films were used for the development of high pulsed magnetic field sensors capable to measure the fields in small volumes independently of magnetic field direction. The influence of macroscopic disorder on the linear magnetoresistive response over a large range of magnetic fields was demonstrated in several inhomogeneous conductors, such as non-stoichiometric silver chalcogenides. Also, 2D graphene and other semimetals such as bismuth, or narrow band gap semiconductors with very low effective mass exhibit linear magnetoresistance up to very high magnetic fields. The possibilities to tailor the magnetoresistive properties of such materials and nanostructures for high magnetic field sensors applications at various ranges of temperatures will be discussed and future perspectives will be outlined.
