Special Issue Information

Dear Colleagues, 

Nanoscale magnetism covers a broad range of research on magnetism and magnetic properties of low-dimensional systems, including both experimental methods in sample fabrication and characterization, as well as theoretical modeling and simulations. Advances in the synthesis techniques of magnetic nanoparticles, thin films, nanowires, nanotubes, and nanodots have contributed to the increased effectiveness of the tailoring of the magnetic properties of high-performance magnetic materials and spintronic devices. A nanomagnetic material exhibits magnetic behaviors that are distinct from those of the bulk form of the same substance because the material’s dimensions are comparable to the critical lengths of one or more of various physical phenomena, such as the size of the magnetic domains. Finite-size effects on the magnetic properties of matter have led to a number of technologically important developments, with an extensive range of applications in sensors and activators, notably in the magnetic recording industry and spintronic devices and, more recently, in biomedical applications. The magnetic state of nanoscale materials results from the equilibrium between competing magnetic anisotropies, interactions, and the applied magnetic field. This can produce a number of phenomena, such as exchange bias effects, skyrmions, as well as magnetic instabilities, which can lead to superparamagnetic effects in magnetic nanoparticles and nanostructures. This Special Issue will contain subjects of interest for researchers in nanoscale magnetism and spintronics. 

This Special Issue “Advances in Nanoscale Magnetism and Spintronics” will be dedicated to gathering recent findings on the synthesis, fabrication, and characterization of nanoscale magnetic materials and devices with potential applications.

Magnetic skyrmions are considered promising candidates for use as information carriers in future spintronic devices. To achieve the development of skyrmion-based spintronic devices, a reasonable and feasible nanotrack is essential. In this paper, we conducted a study on the current-driven skyrmion movement in a circular-ring-shaped nanotrack. Our results suggest that the asymmetry of the inside and outside boundary of the circular ring changed the stable position of the skyrmion, causing it to move like the skyrmion Hall effect when driven by currents. Moreover, the asymmetric boundaries have advantages in enhancing or weakening the skyrmion Hall effect. Additionally, we also compared the skyrmion Hall effect from the asymmetric boundary of circular-ring nanotracks with that from the inhomogeneous Dzyaloshinskii–Moriya interaction. It was found that the skyrmion Hall effect in the circular ring is significantly greater than that caused by the inhomogeneous Dzyaloshinskii–Moriya interaction. These results contribute to our understanding of the skyrmion dynamics in confined geometries and offer an alternative method for controlling the skyrmion Hall effect of skyrmion-based devices.
