Journal of High Energy Physics, 2022 Abstract We study static solutions of the standard Skyrme model with a pion mass. Using approximately 105 pseudo-random initial configurations made of single Skyrmions in the non-symmetrized product Ansatz and an automatic detection of repeated solutions, we find 409 local energy minimizers (Skyrmions) of the model with baryon ...

Van der Waals Heterostructures for Next-Generation Spintronics: Multiferroic-Mediated Magnetoelectric Properties. [PDF]
Adv Sci (Weinh)As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

Collective skyrmion motion under the influence of an additional interfacial spin-transfer torque
Scientific Reports, 2022 Here we study the effect of an additional interfacial spin-transfer torque, as well as the well-established spin–orbit torque and bulk spin-transfer torque, on skyrmion collections—group of skyrmions dense enough that they are not isolated from one ...

Stabilizing magnetic skyrmions in constricted nanowires
Scientific Reports, 2022 Magnetic skyrmions are topologically-protected chiral nano-scale spin structures that offer low power and high-density functionalities for spintronic devices. They behave as particles that can be moved, created and annihilated. These characteristics make

Skyrmion pinning by disk-shaped defects
, 2022 High precision skyrmion pinning by an intentionally created magnetic structure is important in skyrmion manipulation. Here, we consider skyrmion pinning by various types of disks.

Creation of domain-wall Skyrmions in chiral magnets
Nuclear Physics BWe study the capture of a magnetic Skyrmion into a domain wall (DW) structure in chiral magnets and find that in the respective ground states of the DW and the Skyrmion, they repel each other. This means that an isolated magnetic Skyrmion cannot a priori

No skyrmion hair for stationary spherically symmetric reflecting stars
Physics Letters B, 2019 We investigate the existence of the skyrmion field in the background of an asymptotically flat stationary reflecting star. For this purpose, we consider the Einstein-Skyrme system for which there is a skyrmion hair in the black hole case.

Bilayer skyrmion dynamics on a magnetic anisotropy gradient
New Journal of Physics, 2019 Magnetic skyrmion transport has been primarily based on the use of spin torques which require high current densities and face performance deterioration associated with Joule heating.

Dynamic behavior of skyrmion collision: spiral and breath
New Journal of Physics, 2023 A magnetic skyrmion is a particle-like topological soliton, which is an ideal candidate for developing high-density storage and logic devices due to its nonvolatility and tunability.
