Special Issue Information

Dear Colleagues,

In recent years, progress in functional magnetic materials (FMM) and their applications has received wide and increasing attention. Magnetic materials with designs on a molecular or structural scale exhibit excellent functions and are widely utilized for their outstanding features, including their fast, long-range, and precise responses. However, the fundamentals of mechanisms and design in FMM must be fully exploited and utilized for better functions and applications.

This Special Issue aims to publish a collection of cutting-edge original research articles and reviews relating to the most recent efforts on the designs and applications of FMM in various fields, such as magnetic soft robots, magnetic levitation devices, magneto-thermal structures, magnetic-based electronics, magnetically enhanced structures, and magnetic functional devices. Studies on manufacturing and synthesis methods for FMM and advances in functional magnetic field designs are also welcome.

Tactile sensory organs for three-dimensional (3D) force perception are essential for most living organisms and enable them to perform complex and sophisticated tasks to survive and evolve. Magnetic-based tactile sensors have been developed rapidly in recent years due to the exploitability of 3D force decoupling. Here, a method of magnet splicing is introduced, which can be applied to a magnetic tactile sensor to realize 3D self-decoupling of magnets’ displacements. This method enables the magnets to produce a completely consistent magnetic field distribution as the ideal magnetization model within a certain working range, eliminating the compensation and correction of the 3D magnetic flux density signal. This method carves out a new way for the practical application of 3D decoupling theory, showcasing the great potential in the fields of magnetic sensors and magnetic actuators. Full article

Magnetoelectric (ME) laminated composites with strong ME coupling are becoming increasingly prevalent in the electron device field.

Magnetoelectric (ME) laminated composites with strong ME coupling are becoming increasingly prevalent in the electron device field. In this paper, an enhancement of the ME coupling effect via transition-layer implantation for co-fired lead-free laminated composite (80Bi0.5Na0.5TiO3-20Bi0.5K0.5TiO3)/(Ni0.8Zn0.2)Fe2O4 (BNKT/NZFO) was demonstrated. A transition layer composed of particulate ME composite 0.5BNKT-0.5NZFO was introduced between the BNKT piezoelectric layer and the NZFO magnetostrictive layer, effectively connecting the two-phase interface and strengthening interface stress transfer. In particular, an optimal ME voltage coefficients (αME) of 144 mV/(cm·Oe) at 1 kHz and 1.05 V/(cm·Oe) at the resonant frequency in the composite was achieved, with a layer thickness ratio (BNKT:0.5BNKT-0.5NZFO:NZFO) of 3:1:6. The static elastic model was used to determine strong interface coupling. A large magnetodielectric (MD) response of 3.95% was found under a magnetic field excitation of 4 kOe. These results demonstrate that transition-layer implantation provides a new path to enhance the ME response in co-fired laminated composite, which can play an important role in developing magnetic field-tuned electronic devices.
