摘要： PROBLEM TO BE SOLVED: To make it possible to stably record and reproduce information.SOLUTION: A magnetic medium related to one embodiment includes: a first magnetic layer; a second magnetic layer; and a non-magnetic layer. The first magnetic layer is formed of a first magnetic material and records information in response to a direction of magnetization. The second magnetic layer is formed of a second magnetic material of which magnetic anisotropy is different from that of the first magnetic material. The non-magnetic layer is laminated between the first magnetic layer and the second magnetic layer and is formed of a non-magnetic material. The magnetization of the first magnetic layer and the magnetization of the second magnetic layer are antiparallel-coupled to each other by means of exchange action of magnetism via the non-magnetic layer, and the antiparallel-coupling thereof indicates that each magnetization is oriented to opposite directions and is coupled to each other.

摘要： PROBLEM TO BE SOLVED: To provide a silicon/gold seed structure for crystal alignment in a film stack.SOLUTION: A silicon/gold (Si/Au) bilayer seed structure is positioned in a film stack between an amorphous or crystalline lower layer and an upper layer with a well-defined crystalline structure. The seed structure includes an Si layer on the generally flat surface of the lower layer and an Au layer on the Si layer. An Si/Au interface starts the growth of the Au layer with a face-centered-cubic (fcc) crystalline structure having a (111) plane oriented in-plane. The upper layer grown in the Au layer has the fcc or a hexagonal-close-packed (hcp) crystalline structure. If the upper layer is an fcc material, its [111] direction is oriented substantially perpendicular to the (111) plane of the Au layer. If the upper layer is an hcp material, its c axis is oriented substantially perpendicular to the (111) plane of the Au layer.
