| 简介 |
A layer system, a method for forming the layer system, and devices utilizing the layer system are provided. In one embodiment, the method includes providing a bilayer system comprised of a first layer including a first ferromagnetic material doped with a dopant material selected from one of a 4d transition metal, 5d transition metal, and 4f rare earth metal. The dopant material may be predetermined to provide a magnetic damping in the bilayer which is greater than the magnetic damping in the first ferromagnetic material. The first layer may be very thin, e.g., less than or equal to two nanometers thick. The method also includes providing a second layer disposed on the first layer. The second layer includes a second ferromagnetic material and the second layer may be greater than or equal to two nanometers thick. |
