Abstract:
1. A magnetic thin film structure comprising: a first magnetic layer of static off-axis deposited magnetic material with predetermined in-plane magnetic anisotropy consisting of FeCoX, FeCoY, FeCo(X, Y), FeNiX, FeNiCoX, FeNiY, FeNiCoY, FeNi(X, Y), or FeNiCo(X, Y) wherein X is at least one additional transition metal element and Y is at least one rare earth element, and wherein the first magnetic layer has Hk greater than about 25 Oe and maintains thermally stable Hk when subjected to a temperature of 225° C. for two hours; and at least one additional magnetic layer over the first magnetic layer.
