Abstract
The magnetic characteristics of flat and cylindrical permalloy films are compared. 1000 Å-flat films and 10 000-Å cylindrical films electrodeposited onto 5-mil-diameter wires show very similar magnetic properties. Geometrical differences arise largely in the relative ease or difficulty with which fields may be applied to the films and signals extracted. The greater thickness of the cylindrical films described gives rise to enhanced magnetostatic effects apparent in the Kerr effect probe measurements and to strong self-shielding against nonaxial external fields.
