Influence of a perpendicular current on the circulation of a pinned magnetic vortex
The influence of a current’s magnetic field on a vortex pinned in a thin magnetic nanodot is considered. Pinning due to a non-magnetic region or hole in the center of the nanodot is assumed. Then the vortex ground state is planar and has vorticity q = +1, with a double degeneracy due to the two opposite directions (curling or circulation) in which the spins can align around the hole. Dipole int...
متن کاملDynamics of metastable vortex states in weakly pinned superconductors: A phenomenological model
We present a phenomenological model for the vortex dynamics in the peak effect region of weakly pinned superconductors. We explain the history dependent dynamic response of the metastable vortex states subjected to a transport current and the hysteretic voltage-current characteristics observed in the vicinity of peak effect in weakly pinned superconductors. A strong variation in voltage current...
متن کاملEffective Dynamics of a Magnetic Vortex in a Local Potential
We study a gradient-flow version of the Ginzburg-Landau equations with an addition of a compactly supported potential term. We consider initial data close to a magnetic vortex solution of the Ginzburg-Landau equations and find the dynamical law governing the motion of the vortex center in the presence of the potential.
متن کاملSwitching phenomena in magnetic vortex dynamics
A magnetic nanoparticle in a vortex state is a promising candidate for the information storage. One bit of information corresponds to the upward or downward magnetization of the vortex core (vortex polarity). Generic properties of the vortex polarity switching are insensitive of the way how the vortex dynamics was excited: by an ac magnetic field, or by an electrical current. We study theoretic...
