Implementing skyrmion devices in ferromagnetic materials involves issues in common with other spintronic concepts, such as the sensitivity to stray fields. Skyrmions also posses a further complication in that they experience a Magnus force perpendicular to the applied current, making it difficult to move...
Room-temperature skyrmions in ferromagnetic films and multilayers show promise for encoding information bits in new computing technologies. Despite recent progress, ferromagnetic order generates dipolar fields that prevent ultrasmall skyrmion sizes, and
besides the orbital contribution, a spin contribution emerges as well. Our calculations presented in Fig.2have revealed that the orbital Hall conductivity is always much larger than the spin Hall conductivity in a skyrmion sample. Still, it is important to distinguish the individual...
virtually impossible to access with other techniques. This was employed successfully recently to probe the magnetization reconstruction of skyrmion lattices close to the surface,105and could possibly be exploited to access domain information in buried interfaces. Magnetic soft X-ray scattering is unfortunat...
We claim that the underlying physics for the $z = 3$ antiferromagnetic quantum criticality is the emergence of fermionized skyrmion excitations at low energies, which form a Fermi surface, referred as a skyrmion liquid, where the interplay between itinerant electrons and skyrmions is argued to ...
Evolution from Neel order to d-wave superconductivity in the high Tcuprates is described in terms of the skyrmion-like spin texture induced by the doped hole. The pseudogap phase, which is associated with preformed pairs, appears when th... T Morinari - 《Superconductor Science & Technology》...
The motions of a multi-bit, namely the motion of an AFM skyrmion-chain in racetrack, are also investigated. Those micromagnetic simulations may contribute to future AFM skyrmion-based spintronic devices, such as nanotrack memory, logic gates and other information processes....
Skyrmion, a topologically-protected soliton, is known to emerge via electron spin in various magnetic materials. The magnetic skyrmion can be driven by low current density and has a potential to be stabilized in nanoscale, offering new directions of spintronics. However, there remain some fundamental...
half maximum of about 76 nm (Fig.5f), which is likely limited by the flying distance of the NV spin sensor. These results are in line with MFM measurements performed under vacuum on similar samples8. Despite the fact that the internal breathing mode frequencies of the skyrmion are larger...
