Domain wall motion in thin ferromagnetic nanotubes: Analytic results [PDF]

open access: yes, 2014
Dynamics of magnetization domain walls (DWs) in thin ferromagnetic nanotubes subject to weak longitudinal external fields is addressed analytically in the regimes of strong and weak penalization.

A Novel Design of a 3D Racetrack Memory Based on Functional Segments in Cylindrical Nanowire Arrays

open access: yesNanomaterials, 2020
A racetrack memory is a device where the information is stored as magnetic domains (bits) along a nanowire (track). To read and record the information, the bits are moved along the track by current pulses until they reach the reading/writing heads.

Efficient in-line skyrmion injection method for synthetic antiferromagnetic systems

open access: yesNew 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.

Magnetic skyrmions and domain walls for logical and neuromorphic computing

open access: yesNeuromorphic 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 ...

CHARGED DOMAIN WALLS

open access: yesInternational 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 ...

Interaction of a breather with a domain wall in a two-dimensional O(3) nonlinear sigma model [PDF]

open access: yesКомпьютерные 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]

open access: yes, 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

open access: yesEcoMat, 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 ...

Magneto-optical imaging of the domain wall distortions enhanced by magnetic fields in amorphous glass-coated microwire

open access: yesAIP 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 ...
