Magnonic Spin-Transfer Torque and Domain Wall Propagation

IEEE Transactions on Magnetics, 2012
Magnonic spin-transfer torque (STT) is introduced. In comparison with electronic STT, magnonic STT is more efficient in driving domain wall (DW) propagation along a magnetic nanowire because of the total spin wave transmission through a DW. Furthermore, the energy consumption is more than millions times lower than that by electronic STT when the ...

Modification of domain-wall propagation in Co nanowires via Ga+ irradiation [PDF]

European Physical Journal B, 2013
The propagation of domain walls in polycrystalline Co nanowires grown by focused-electron-beam-induced deposition is explored. We have found that Ga+ irradiation via focused ion beam is a suitable method to modify the propagation field of domain walls in

Domain wall propagation in meso- and nanoscale ferroelectrics

Journal of Physics: Condensed Matter, 2011
As part of an ongoing programme to evaluate the extent to which external morphology alters domain wall mobility in ferroelectrics, the electrical switching characteristics of single-crystal BaTiO(3) nanorods and thin film plates have been measured and compared.

Effect of domain walls on the propagation of microwaves

Soviet Physics Journal, 1985
The propagation of microwaves in ferrimagnets is affected mainly by the gyrotropic terms of the magnetic permeability tensor, due in this frequency range to ferromagnetic and exchange resonances. It is shown that the change in the gyrotropic terms in the domain wall region leads to the existence of a localized mode propagating close to the domain wall.

Domain wall propagation in micrometric wires: Limits of single domain wall regime

Journal of Applied Physics, 2012
We measured magnetic domain propagation and local domain wall(DW) nucleation in Fe-Co-rich amorphous microwires with metallic nucleus diameters from 2.8 to 18 μm. We found that manipulation of magnetoelastic energy through application of applied stresses, changing of magnetostriction constant, and variation of internal stresses through changing the ...

Dynamic propagation and nucleation in domain wall nanowire devices

Journal of Physics: Condensed Matter, 2011
The dynamic injection and propagation of domain walls (DWs) in technologically relevant geometries have been investigated. On short (~10 ns) timescales nucleation of a DW by a localized Oersted field is found to be well described using a Néel-Brown reversal mode.

Solitons and Propagating Domain Walls in Topological Resonator Arrays

ACS Photonics, 2017
An array of linear resonators with alternating linear–nonlinear bonds can transition from a topologically trivial to a nontrivial band structure as a function of the applied intensity. Here, we demonstrate that edge modes supported by the topology of the band diagram in such arrays can evolve into solitons, sustained by propagating domain walls induced

Magnetoelastic Contribution in Domain Wall Propagation of Micrometric Wires

Journal of Nanoscience and Nanotechnology, 2012
We report on studies of domain wall propagation of magnetically-bistable Fe-Co-rich microwires paying attention on the effect of applied and internal stresses. We measured magnetic domain propagation in various magnetic Fe-Co-rich amorphous microwires with metallic nucleus diameters (from 2.8 microm to 18 microm) using Sixtus Tonks-like experiments. We

Step-Edge Induced Anisotropic Domain-Wall Propagation

Physical Review Letters, 2000
We report the observation of anisotropic domain-wall propagation in ultrathin magnetic films with perpendicular anisotropy. A controlled density of step edges was introduced which allowed us to quantify its influence on the domain-wall pinning. For a sawtooth arrangement of the step edges the corresponding wall movement resulted in triangular shaped ...
