FFundamental understanding of magnetization dynamics in a system with a reduced dimensionality is essential in the future advancements of nanomagnetism.Thus, it becomes important to explore the magnetization oscillations in sub-micron magnetic particles such as dots.For mesoscopic and nanoscale sizes of dots, non-uniform magnetization distribu tions with zero remanence (" vortex" states) are often observed at equilibrium.The vortex states can be stable within a wide range of dot sizes from a few tens of nm up to a few tens of microns.Vortex related phenomena offer insight into magnetization dynamics on a fundamental level, and also govern magnetization reversal.
