Abstract: A film of magnetic amorphous material capable of supporting bubble domains containing a region therein having a canted direction of magnetic uniaxial anisotropy is described. An example is a magnetic amorphous film having bubble domains therein in which the magnetic uniaxial anisotropy is canted at an angle of 5 DEG from a line perpendicular to the plane of the film. Another example is a film of magnetic amorphous material containing one layer having the magnetic uniaxial anisotropy canted in one direction and a second layer having the magnetic uniaxial anisotropy canted in another direction.
