Abstract: Using a gene recombination technique, a glutamic acid and an aspartic acid positioned in a channel of apoferritin are substituted with serine having a small size and no charges. Then, a glutamic acid positioned in a holding portion is substituted with a basic amino acid such as lysine or a neutral amino acid. Furthermore, at least one cysteine is introduced into the holding portion. This prevents a repulsive force due to electrostatic interaction between (AuCl4)? having a negative charge and a negative amino acid from occurring, which facilitates the capture of (AuCl4)? into the channel and the holding portion. The (AuCl4)? captured into the holding portion is subsequently reduced to Au, and thus apoferritin including gold particles can be produced.

Abstract: A magnetic recording medium for data storage uses a magnetic recording layer having at least two ferromagnetic films with different remanent magnetization-thickness (Mrt) values that are coupled antiparallel across a nonferromagnetic spacer film predominantly by the dipole field (Hd) from the grains of the higher-Mrt ferromagnetic film.
