| 简介 |
A device including a magnetic structure having a substrate adjacent surface and a second, opposing surface and including a NFT that includes gold or an alloy thereof, and is positioned at the second surface; an overcoat structure; and a film structure positioned between the magnetic structure and the overcoat structure, the film structure having a total thickness of not greater than about 100 Å, and including : a first interfacial structure; a second interfacial structure; and an intermediate structure positioned adjacent the NFT of the magnetic structure, and the second interfacial structure positioned adjacent the overcoat structure, and the intermediate structure positioned between the first interfacial structure and the second interfacial structure, and wherein the first interfacial structure includes one or more rare earth elements, one or more alkaline earth metals, one or more alkali metals, or a combination thereof. |
