摘要:
A process for producing a nano-structure is provided which enables control of the pore diameters and the pore intervals by film formation conditions. The process produces a nano-structure of an aluminum-silicon-germanium mixed film containing silicon and germanium at a content of 20 to 70 atom % relative to aluminum, the mixed film being constituted of a matrix composed mainly of silicon and germanium in a composition ratio of SixGe1-x (0≦X≦1), and cylindrical portions mainly composed of aluminum having a diameter of not larger 30 nm in the matrix. In the process, the mixed film is formed at a film-forming rate of not higher than 150 nm/min.

摘要:
A magnetic device has a layer containing fine pores and having wirings on both faces of the layer formed on a substrate, wherein at least a part of the pores are filled with a layered column formed by stacking magnetic layers and nonmagnetic layers alternately, and at least a part of the pores filled with a conductive column as writing wires for writing into the magnetic layers in the adjacent pores. The fine pores may be nano-holes of alumina formed by anodic oxidation. A part of the pores may serve to intercept a magnetic field. The magnetic layer may contain Co, and the nonmagnetic layer and/or the writing wire may contain Cu. The pores may be arranged in a honeycomb arrangement or a rectangular array. The ratio of the sectional area S (cm2) of the pore and the length (cm) of the pore satisfy the relation: 105 105.
