摘要

This Rapid Communication reports the solution of the equation of motion for a domain wall in a magnetic material which exhibits high magnetocrystalline 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.
