<p>In accordance with the present invention, ferromagnetic thin films of iron that have reduced relaxation rates and methods of making the same are provided. It should be noted that pure iron is a ferromagnet (i.e., has a spontaneous magnetization alignment) with the lowest intrinsic damping rate of all of the ferromagnets. The present invention provides a ferromagnetic structure comprising a substrate and a ferromagnetic thin film of iron (Fe) formed on the substrate. An element selected from the group consisting of titanium (Ti), vanadium (V), chromium (Cr), and manganese (Mn) (i.e., a lower-Z transition metal element) is alloyed with the ferromagnetic thin film of iron to reduce the relaxation rate of the ferromagnetic thin film.</p> |
