Magnetization reversal in patterned permalloy single domain elements

This paper presents magnetization reversal in patterned single domain magne tic elements. The experimental setup consisted of elliptical permalloy elem ents produced on top of a pl pre-formatted gold strip. The external magneti c field was applied through the permalloy elements by passing electrical cu rrent through the gold strip. Magnetic force microscopy images of the patte rned elements after various electrical currents were applied demonstrated t he magnetization reversal.
