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 ...

Domain wall propagation in adiabatic regime

Physica B: Condensed Matter, 2008
Abstract The domain wall dynamics in the adiabatic regime has been studied. It is shown that the domain wall velocity in the low-field range (when the domain wall interacts with the distributed defects) satisfy the power law: v = S ′( H − H 0 ) β , where H 0 is the critical field. The temperature dependence of the power exponent β is treated

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.

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 ...

Domain wall propagation in Fe-rich microwires

Physica B: Condensed Matter, 2008
We studied the velocity of domain wall propagation, v, of Fe 69 Si 10 B 15 C 6 with different metallic nucleus diameter, d, and different total diameter, D (d = 14 μm, D = 33 μm and d= 18 μm, D = 23.4μm, respectively) in the temperature range between 78 and 300K and at different frequencies of applied magnetic field.

Domain Wall Propagation in Thin Magnetic Wires

IEEE Transactions on Magnetics, 2008
We present the domain wall dynamics in amorphous glass-coated microwires. It is described by the linear dependence of the domain wall velocity on the applied magnetic field. For higher Ni content microwires, the domain wall dynamics consists of two regions: at low field, the domain wall has low mobility and a negative critical propagation field.

Automotive domain wall propagation in ferromagnetic rings

2015 IEEE Magnetics Conference (INTERMAG), 2015
Automotive domain wall propagation is a self-propelling motion utilizing the energy stored in a particular energy reservoir of the spin structure to speed up domain wall beyond its equilibrium value given by external driving force and damping. Such a concept of DW motion is of great interest due to recent development of spintronic devices based on ...

Domain Wall Propagation in Wavy Ferromagnetic Nanowire

IEEE Transactions on Magnetics, 2009
We have investigated magnetic domain wall propagation behavior in wavy nanowires using micromagnetic simulation. The wire width is set to have sinusoidal distortion with variation of spatial frequency and phase. We have analyzed domain wall speed under a constant external field with variation of wavy geometry. Interestingly, with introduction of proper

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
