Domain wall propagation through spin wave emission [PDF]

Physical Review Letters, 2012
We theoretically study field-induced domain wall (DW) motion in an electrically insulating ferromagnet with hard- and easy-axis anisotropies. DWs can propagate along a dissipationless wire through spin wave emission locked into the known soliton velocity

Boosting Domain Wall Propagation by Notches [PDF]

Physical Review B, 2015
We report a counter-intuitive finding that notches in an otherwise homogeneous magnetic nanowire can boost current-induced domain wall (DW) propagation.

High velocity domain wall propagation using voltage controlled magnetic anisotropy. [PDF]

Sci Rep, 2019
AbstractThe use of voltage-controlled magnetic anisotropy (VCMA) via the creation of a sloped electric field has been hailed as an energy-efficient approach for domain wall (DW) propagation. However, this method suffers from a limitation of the nanowire length which the DW can propagate on.

Light wave propagation through a dilaton-Maxwell domain wall [PDF]

Physical Review D, 2015
We consider the propagation of electromagnetic waves through a dilaton-Maxwell domain wall of the type introduced by Gibbons and Wells [G.W. Gibbons and C.G. Wells, Class. Quant. Grav. 11, 2499-2506 (1994)].

Field-induced domain wall propagation velocity in magnetic nanowires

, 2009
A thory of field-induced domain wall (DW) propagation is developed. The theory not only explains why a DW in a defect-free nanowire must propagate at a finite velocity, but also provides a proper definition of DW propagation velocity.

Domain wall mobility engineering by a perpendicular magnetic field in microwires with a gradient of perpendicular anisotropy

AIP Advances, 2021
Fast domain wall propagation is a typical feature of amorphous glass-coated microwires with positive magnetostriction. The high domain wall velocity can be effectively tailored either by sample postprocessing or temperature.

All-Magnonic Spin-Transfer Torque and Domain Wall Propagation [PDF]

Physical Review Letters, 2011
The spin wave transportation through a transverse magnetic domain wall (DW) in a magnetic nanowire is studied. It is found that spin wave passes through a DW without reflection. A magnon, the quantum of the spin wave, carries opposite spins on the two sides of the DW.
