WebSep 21, 2024 · Magnetic skyrmions are chiral spin-structure quasi-particles that form two-dimensional lattices. Here, in this study, we show, by real-space imaging using in situ cryo … WebOct 5, 2024 · In order to obtain skyrmion clusters, we place in an initially saturated configuration in the + z -direction, N circular and localized antiparallel regions (in the - z -direction). This magnetic configuration is relaxed by minimizing the total energy U [ m] until the condition m × H eff = 0 is satisfied and a steady state is reached (see Fig. 1 b).

WebThese ac fields act as a net driving force on the Skyrmion via its own intrinsic magnetic excitations. In a microscopic quantum field theory approach, we include the unavoidable … WebApr 14, 2024 · Charge and spin density waves are typical symmetry broken states of quasi one-dimensional electronic systems. They demonstrate such common features of all incommensurate electronic crystals as a spectacular non-linear conduction by means of the collective sliding and susceptibility to the electric field. These phenomena ultimately … the016

WebSkyrmions Driven by Intrinsic Magnons: Christina Psaroudaki and Daniel Loss. Phys. Rev. Lett. 120, 237203 (2024) We study the dynamics of a skyrmion in a magnetic insulating nanowire in the presence of time-dependent oscillating magnetic field gradients. These ac fields act as a net driving force on the skyrmion via its own intrinsic magnetic ... WebJun 8, 2024 · These ac fields act as a net driving force on the Skyrmion via its own intrinsic magnetic excitations. In a microscopic quantum field theory approach, we include the unavoidable coupling of the external field to the magnons, which gives rise to time … WebMay 26, 2024 · Wave fields with spiral phase dislocations carrying orbital angular momentum (OAM) have been realized in many branches of physics, such as for photons, sound waves, electron beams, and neutrons. However, the OAM states of magnons (spin waves)—the building block of modern magnetism—and particularly their implications have … the013
