Special Issue Information

Dear Colleagues,

Magnetic sensors and actuators are playing an increasingly important role in most industries, such as electrical engineering, medicine, computer science, construction monitoring, electronic surveillance, automotive or aviation industries. It is expected that the global market for magnetic sensors and actuators will grow due to high demand from the rapidly growing industries mentioned above. Therefore, the development of high-performance sensors and actuators adapted to the requirements of the industries has attracted increasing attention from researchers and engineers working in sensorics.

Recent trends in magnetic sensorics are based on fundamental research and the use of new materials and phenomena and are focused on miniaturization of sensors and actuators, improving their characteristics, searching for new operating principles, and developing new magnetic materials.

This Special Issue will be focused on the latest scientific results, the latest developments, novel ideas on the development of highly sensitive magnetic devices and applications, magnetic sensing technology, basic phenomena and fundamental studies of new magnetic materials suitable for magnetic sensors, actuators and applications, as well as wireless nondestructive control and monitoring, wearable electronics, and medicine using magnetic sensors.

Both reviews and original research papers will be considered. Review papers should provide an up-to-date, well-balanced overview of the current state-of-the-art in a particular application and include the main results from other groups.

The topics of this Special Issue encompass but are not restricted to the following areas:

  • Magnetic sensors and actuators including Hall-effect devices, magnetometers, magnetoimpedance sensors, magnetoresistance sensors, magnetoelastic sensors, and flexible electronics;
  • Novel and advanced magnetic materials for sensor and actuator applications and their advanced processing;
  • Fundamentals and physics involving basic effects, theory, and modeling of magnetic sensors;
  • Magnetic measurements and instrumentation, measurement standards;
  • Smart materials and composites for wireless and nondestructive monitoring of external stimuli, including tunable metamaterials;
  • Development of magnetic sensor and actuator applications, including in the biomedicine, electronic surveillance, electrical engineering, informatics, magnetic recording, construction monitoring, automobile and aircraft industries, among others.

This special issue is focused more on sensors. Papers focus on actuators may choose our joint special issue in Actuators (ISSN 2076-0825, IF 1.975).

We look forward for your valuable contributions to this Special Issue.

Tuning of Magnetoimpedance Effect and Magnetic Properties of Fe-Rich Glass-Coated Microwires by Joule Heating

The influence of Joule heating on magnetic properties, giant magnetoimpedance (GMI) effect and domain wall (DW) dynamics of Fe75B9Si12C4 glass-coated microwires was studied. A remarkable (up to an order of magnitude) increase in GMI ratio is observed in Joule heated samples in the frequency range from 10 MHz to 1 GHz. In particular, an increase in GMI ratio, from 10% up to 140% at 200 MHz is observed in Joule heated samples. Hysteresis loops of annealed samples maintain a rectangular shape, while a slight decrease in coercivity from 93 A/m to 77 A/m, after treatment, is observed. On the other hand, a modification of MOKE hysteresis loops is observed upon Joule heating. Additionally, an improvement in DW dynamics after Joule heating is documented, achieving DW propagation velocities of up to 700 m/s. GMI ratio improvement along with the change in MOKE loops and DW dynamics improvement have been discussed considering magnetic anisotropy induced by Oersted magnetic fields in the surface layer during Joule heating and internal stress relaxation. A substantial GMI ratio improvement observed in Fe-rich Joule-heated microwires with a rectangular hysteresis loop and fast DW propagation, together with the fact that Fe is a more common and less expensive metal than Co, make them suitable for use in magnetic sensors.

Ceramic-chromium Hall sensors represent a temperature and radiation resistant alternative to Hall sensors based on semiconductors. Demand for these sensors is presently motivated by the ITER and DEMO nuclear fusion projects. The developed ceramic-chromium Hall sensors were tested up to a temperature of 550 °C and a magnetic field of 14 T. The magnitude of the sensitivity of the tested sensor was 6.2 mV/A/T at 20 °C and 4.6 mV/A/T at 500 °C. The sensitivity was observed to be weakly dependent on a temperature above 240 °C with an average temperature coefficient of 0.014%/°C and independent of the magnetic field with a relative average deviation below the measurement accuracy of 0.086%. A simulation of a neutron-induced transmutation was performed to assess changes in the composition of the chromium. After 5.2 operational years of the DEMO fusion reactor, the transmuted fraction of the chromium sensitive layer was found to be 0.27% at the most exposed sensor location behind the divertor cassette with a neutron fluence of 6.08 × 1025 n/m2. The ceramic-chromium Hall sensors show the potential to be suitable magnetic sensors for environments with high temperatures and strong neutron radiation. Full article

Ferrimagnetic thin films formerly played a very important role in the development of information storage technology. Now they are again at the forefront of the rising field of spintronics. From new, more efficient magnetic recording media and sensors based on spin valves to the promising technologies envisaged by all-optical switching, ferrimagnets offer singular properties that deserve to be studies both from the point of view of fundamental physics and for applications. In this review, we will focus on ferrimagnetic thin films based on the combination of rare earths (RE) and transition metals (TM). Full article

Amorphous soft magnetic microwires have attracted much attention in the area of sensor applications due to their excellent properties. In this work, we study the influence of annealing treatments (stress and conventional) in the giant magnetoimpedance (GMI) response and the field sensitivity of the soft magnetic Co69.2Fe3.6Ni1B12.5Si11Mo1.5C1.2 glass-coated microwires. Here we report a remarkable and simultaneous enhancement of GMI effect and field sensitivity. The highest sensitivity of 104%/Oe and the GMI response of 234% were achieved for 300 °C stress-annealed samples at 472 and 236 MPa, respectively. Additionally, we found that stress-annealed microwires exhibit a frequency dependence on maximal GMI response and field sensitivity. These findings are obtained by fine-tuning their magnetoeslastic anisotropies through stress-annealing treatments of as-prepared microwires at the proper temperature and axial applied stress upon annealing. We hope that the results presented here widen the scope of investigations for the future design of soft magnetic materials for sensor purposes. Full article
