Abstract
The magnetic characteristics of cylindrical electroplated films are considered. Pertinent previous work is reviewed and new data are presented which elucidate the following items: (a) Preparation. The influence of surface roughness is emphasized, and important recent work on surface topology is reviewed. (b) Magnetic Characterization. The use of susceptibility measurements to determine the anisotropy and the ripple amplitude are discussed. When the ripple amplitude is large, previous calculations of the susceptibility based on the linear ripple theory do not apply. Nevertheless, it is possible to use the susceptibility to characterize the anisotropy and dispersion if the susceptibility is described in terms of a phenomenological ripple field picture. (c) Domain Wall Creeping. The possible causes of creep in thick films are considered. From the thickness dependence of the creep threshold, it does not appear that the Olson‐Torok model is adequate. Data on the creep velocity are presented. Finally, a model for creep is described which hinges on the distribution of wall motion fields along the wall. (d) Thermal Stabilization. It is shown that by annealing at elevated temperatures, adequate thermal stabilization of plated films can be achieved.Keywords
