Stability of magnetic configurations in nanorings
arXiv:cond-mat/0608037 · doi:10.1063/1.2218997
Abstract
The relative stability of the vortex, onion and ferromagnetic phases in nanorings is examined as a function of the ring geometry. Total energy calculations are carried out analytically, based on simple models for each configuration. Results are summarized by phase diagrams, which might be used as a guide to the production of rings with specific magnetic properties.
