TITANIUM OXIDE THIN FILM, PROCESS FOR PRODUCING THE SAME, MAGNETIC MEMORY, OPTICAL INFORMATION RECORDING MEDIUM, AND CHARGE STORAGE MEMORY

摘要

PROBLEM TO BE SOLVED: To provide a titanium oxide thin film exhibiting non-conventional new properties, a process for producing the thin film, and a magnetic memory, an optical information recording medium and a charge storage memory produced, by using the thin film.

SOLUTION: A raw material solution containing TiO2particles is applied onto the surface of a substrate 2 to form a TiO2particle layer on the surface of the substrate 2, and the substrate 2 is burned under a hydrogen atmosphere to form a titanium oxide thin film 3 on the surface of the substrate 2. In this manner, it becomes possible to provide the titanium oxide thin film 3 which does not undergo phase transition at room temperature unlike conventional bulk materials that undergo the phase transition between a non-magnetic semiconductor and a paramagnetic metal at about 460K, and therefore has such a new and non-conventional property that the Ti3O5particles themselves can keep the properties of a paramagnetic metal at any time in any temperature range.
