Abstract
Featured is a magnetic ring structure including at least a vortex magnetic state such as symmetrically and asymmetrically shaped nanorings (FIG.C), having small diameters (e.g., on the order of 100 run). In particular embodiments, the width and thickness of the maxima and minima thereof are located on opposite sides of the nanoring. Also featured are methods for fabricating such symmetrically and asymmetrically shaped nanorings (FIG.). Also featured are methods for controlling the reversal process so as to thereby create vortex states in such asymmetric nanorings by controlling the field angle (FIG.).
