摘要

A method of fabricating anisotropic magnetic films includes providing a substrate (18), sputtering a layer (24) of NixFey (where x ranges from 40 to 50 and y = (100-x)) onto a surface (28) of the substrate, and subjecting the layer of NixFey to a rotating magnetic field (36) during the sputtering deposition process. A magnetic storage medium comprising a substrate (128), a soft magnetic underlayer (126) supported by the substrate, the soft magnetic underlayer including NixFey (where x ranges from 40 to 50 and y = (100-x)) and having an easy axis in a circumferential direction and a hard axis in a radial direction, and a magnetically hard recording layer (124) supported by the soft magnetic underlayer, is also included.
