Abstract: An apparatus includes a substrate and a magnetic layer coupled to the substrate. The magnetic layer includes an alloy that has magnetic hardness that is a function of the degree of chemical ordering of the alloy. The degree of chemical ordering of the alloy in a first portion of the magnetic layer is greater than the degree of chemical ordering of the alloy in a second portion of the magnetic layer, and the first portion of the magnetic layer is closer to the substrate than the second portion of the magnetic layer.
