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 TiOparticles is applied onto the surface of a substrate 2 to form a TiOparticle 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 TiOparticles themselves can keep the properties of a paramagnetic metal at any time in any temperature range.

摘要： PROBLEM TO BE SOLVED: To provide titanium oxide particles capable of exhibiting non-conventional new material properties, a process for producing the particles, and a magnetic memory, an optical information recording medium, and a charge storage memory formed, by using the particles.SOLUTION: Titanium hydroxide compound particles coated with silica are directly produced by a sol-gel method without using a reverse micelle method, and the silica-coated titanium hydroxide compound particles are burned. By the production process, it is possible to provide titanium oxide particles 1 capable of exhibiting non-conventional new material properties which enable TiOparticles themselves to always retain the nature of a paramagnetic metal throughout the whole temperature range without undergoing the phase transition at room temperature, unlike conventional bulk materials that undergo phase transitions between a non-magnetic semiconductor and a paramagnetic metal at about 460K.

摘要： PROBLEM TO BE SOLVED: To provide a titanium oxide particle that can exhibit conventionally nonexistent novel physical properties, an optical information recording medium, a method for producing the same, and a magnetic memory and charge storage memory using the same.SOLUTION: Disclosed is a titanium oxide particle 1 that can exhibit conventionally nonexistent novel physical properties such that, when TiOparticle body 2 is formed, the particle takes a form in which silica glass that has coated the surface of the TiOparticle body 2 is removed. Furthermore, unlike a conventional bulk body that undergoes phase transition to a nonmagnetic semiconductor and a paramagnetic metal in the neighborhood of a temperature of approximately 460 K, the TiOparticle body does not undergo a phase transition at room temperature and can always maintain the characteristics of a paramagnetic metal in all temperature ranges.
