Analytical solution of the equation of motion for a rigid domain wall in a magnetic material with perpendicular anisotropy
arXiv:0807.2604 · doi:10.1103/PhysRevB.78.180412
Abstract
This paper reports the solution of the equation of motion for a domain wall in a magnetic material which exhibits high magneto-crystalline anisotropy. Starting from the Landau-Lifschitz-Gilbert equation for field-induced motion, we solve the equation to give an analytical expression, which specifies the domain wall position as a function of time. Taking parameters from a Co/Pt multilayer system, we find good quantitative agreement between calculated and experimentally determined wall velocities, and show that high field uniform wall motion occurs when wall rigidity is assumed.
