Anisotropy modification and domain-wall behavior in grooved films

Patterns of 5-μm-wide grooves on 25-μm centers were partially etched in the easy and/or hard directions in uniaxial Permalloy films; 20-μm-diameter circles or 25-μm centers were also etched. The easy direction grooves modified the anisotropy of the films to produce an NDRO behavior, while the hard d... View More
