New Journal of Physics, 2019 Domain wall motion (DWM) by spin waves (SWs) in different waveforms in a magnetic nanostripe is investigated via micromagnetic simulations. Diversified DWMs are observed. It is found that SW harmonic drives DWM most efficiently and irregular SW may cause

Magnetic skyrmions and domain walls for logical and neuromorphic computing
Neuromorphic Computing and Engineering, 2023 Topological solitons are exciting candidates for the physical implementation of next-generation computing systems. As these solitons are nanoscale and can be controlled with minimal energy consumption, they are ideal to fulfill emerging needs for ...

Efficient in-line skyrmion injection method for synthetic antiferromagnetic systems
New Journal of Physics, 2018 Although it has been proposed that antiferromagnetically-coupled skyrmions can be driven at extremely high speeds, such skyrmions are near impossible to inject with current methods.

Interaction of a breather with a domain wall in a two-dimensional O(3) nonlinear sigma model [PDF]
Компьютерные исследования и моделирование, 2017 By numerical simulation methods the interaction processes of oscillating soliton (breather) with a 180-degree Neel domain wall in the framework of a (2 + 1)-dimensional supersymmetric O(3) nonlinear sigma model is studied. The purpose of this paper is to

Barkhausen Noise from Precessional Domain Wall Motion [PDF]
, 2019 The jerky dynamics of domain walls driven by applied magnetic fields in disordered ferromagnets - the Barkhausen effect - is a paradigmatic example of crackling noise. We study Barkhausen noise in disordered Pt/Co/Pt thin films due to precessional motion

Ferroic alternation in methylammonium lead triiodide perovskite
EcoMat, 2021 Methylammonium lead triiodide (MAPbI3) perovskite has attracted broad interest for solar cells, light‐emitting diodes, and so forth. Experiments have captured that the alternative coexistence of polar and nonpolar domains in MAPbI3 can be switched by ...

Physics Letters B, 1985 Abstract It is shown that superconducting domain walls readily appear in realistic SO(10) and E6 grand unified theories. Although topologically unstable, they may survive in some cases till cosmic time t ∼ 105−107 s with possibly significant cosmological and astrophysical consequences.

International Journal of Modern Physics D, 2004 In this paper we investigate Charged Domain Walls (CDW's), topological defects that acquire surface charge density Q induced by fermion states localized on the walls. The presence of an electric and magnetic field on the walls is also discussed. We find a relation in which the value of the surface charge density Q is connected with the existence of ...

AIP Advances, 2023 Here, we employ time-resolved magneto-optical Kerr system (MOKE) imaging to ascertain the origin of domain wall motion in microwires. The MOKE visualisations of the domain walls motion on the surface of the microwires prove the domain wall pinning and ...
