Magnetic domain wall propagation under ferroelectric control

Physical Review B, 2012
Control of magnetic domain walls (DWs) and their propagation is among the most promising development directions for future information-storage devices. The well-established tools for such manipulation are the spin-torque transfer from electrical currents and strain.

Multistep Bloch-line-mediated Walker breakdown in ferromagnetic strips [PDF]

, 1978
A well-known feature of magnetic field driven dynamics of domain walls in ferromagnets is the existence of a threshold driving force at which the internal magnetization of the domain wall starts to precess -- a phenomenon known as the Walker breakdown --

Current-driven spiral domain wall in a ferrimagnet near the magnetization compensation point

Physical Review Research, 2022
A spiral domain wall emerges when the Dzyaloshinskii-Moriya vector is along the easy axis. While the ferromagnetic spiral wall has been well studied, its ferrimagnetic counterpart has nevertheless not been explored.

Magnetic domain wall propagation in a submicron spin-valve stripe: influence of the pinned layer

, 2008
The propagation of a domain wall in a submicron ferromagnetic spin-valve stripe is investigated using giant magnetoresistance. A notch in the stripe efficiently traps an injected wall stopping the domain propagation.

Magnetic domain-wall motion by propagating spin waves [PDF]

Applied Physics Letters, 2009
We found by micromagnetic simulations that the motion of a transverse wall (TW)–type domain wall in magnetic thin-film nanostripes can be manipulated via interaction with spin waves (SWs) propagating through the TW. The velocity of the TW motion can be controlled by changes of the frequency and amplitude of the propagating SWs.

Controlling the domain wall dynamics in Co-rich magnetic microwires with graded magnetic anisotropy

Journal of Science: Advanced Materials and Devices
We have shown after annealing Co-rich microwire in a temperature gradient, graded magnetic anisotropy is observed. In studied microwires annealed at variable temperatures, a gradual change in hysteresis loops along the length of the microwire from ...

Subsystem domination influence on magnetization reversal in designed magnetic patterns in ferrimagnetic Tb/Co multilayers

Scientific Reports, 2021
Recent results showed that the ferrimagnetic compensation point and other characteristic features of Tb/Co ferrimagnetic multilayers can be tailored by He+ ion bombardment.

Propagation of a magnetic domain wall in magnetic wires with asymmetric notches [PDF]

, 2004
The propagation of a magnetic domain wall (DW) in a submicron magnetic wire consisting of a magnetic/nonmagnetic/magnetic trilayered structure with asymmetric notches was investigated by utilizing the giant magnetoresistance effect.

A fourier pseudospectral method for some computational aeroacoustics problems

, 2006
A Fourier pseudospectral time-domain method is applied to wave propagation problems pertinent to computational aeroacoustics. The original algorithm of the Fourier pseudospectral time-domain method works for periodical problems without the interaction ...
