Abstract:
A method for forming an ordered alloy includes: (a) forming a layer of a first metal with a layer thickness of less than 0.3 nm over a substrate; (b) forming a layer of a second metal with a layer thickness of less than 0.3 nm on the layer of the first metal under an elevated temperature sufficient to cause interdiffusion of atoms of the first and second metals between the layer of the first metal and the layer of the second metal so as to form the ordered alloy; and (c) repeating steps (a) and (b) until a predetermined layer thickness of the ordered alloy is achieved.
Abstract:
A method for ordering a disordered alloy includes: simultaneously ion bombarding and annealing a disordered alloy to transform the disordered alloy from a disordered crystalline state to an ordered crystalline state. A method for making a perpendicular magnetic recording medium which includes an ordered alloy layer is also disclosed.

Abstract:
A novel heat assisted magnetic recording (HAMR) medium and the fabrication method therefor are provided. The exchange coupling effect occurring at the interface of FePt/CoTb double layers is adopted, and thus the resulting magnetic flux would be sufficient enough to be detected and readout under the room temperature. The provided HAMR medium exhibits a relatively high saturation magnetization and perpendicular coercivity, and thus possesses a great potential for the ultra-high density recording application.

Abstract:
A magnetic recording medium having at least an adjustable magnetic property is provided. The provided magnetic recording medium includes a substrate and a layer sequence located thereon. The layer sequence includes a underlayer, a buffer layer and a recording layer made of a magnetic material. According to the present invention, the adjustable magnetic property of the magnetic recording medium is adjusted via the variation of the thickness of the underlayer.
