摘要： A raw material mixed solution containing nitrate or alkoxide of metal that constitutes a ferrite is sprayed from an atomizer by means of a carrier gas such as compressed air onto a substrate mounted on a hot plate and heated to a predetermined temperature. The method enables a thin film having a desired thickness to be formed by a simple apparatus in a short time without sacrificing good soft magnetism of a ferrite, thereby greatly contributing to downsizing and weight reduction of electronic devices.

摘要： A magnetic head which can be miniaturized while maintaining the performance thereof includes a thin film conductor coil assembly having a magnetic core connected magnetically to magnetic substances and stepping across a non-magnetic substance located between the magnetic substances of a substrate and a thin film conductor coil formed with the magnetic core as a thin film magnetic core. This thin film conductor coil assembly is attached to a slider provided with a magnetic head core. The magnetic head core includes an I-core in which magnetic substances are formed on both sides of a non-magnetic substance, and a U-shaped core composed of a magnetic substance, formed together in one integral body with a magnetic gap provided therein. This magnetic head core is fitted into a slit in the slider, and the thin film conductor coil assembly is attached thereon. With this construction, it is possible to form the thin film conductor coil into a thin film and to enlarge the magnetic path area, thereby to miniaturize the magnetic head while maintaining the performance thereof.

摘要： A reflection type Faraday rotator includes first to sixth reflection type sub-rotators. Light is made incident on the first to sixth sub-rotators while repeating reflecting thereat. A Faraday rotation occurs at a sub-rotator having a center wavelength equal to the wavelength of the light The sub-rotators are of reflection-type, have a larger bandwidth of outgoing light compared to a transmission type, and have center wavelengths (wavelength characteristics) different from one another. Thus, the effective wavelength range (the wavelength bandwidth) is increased. Expensive optical devices conventionally required for increasing the wavelength bandwidth are not needed. Accordingly, the cost can be reduced.

In the Faraday rotator, a metal reflective film is formed on a substrate, then a first periodic dielectric multilayer film made of silicon dioxide SiO2 and tantalum pentaoxide Ta2O5, a magneto-optical thin film, and a second periodic dielectric multilayer film made of tantalum pentaoxide Ta2O5 and silicon dioxide SiO2 are formed sequentially. The number of layers of the first periodic dielectric multilayer film is larger than that of the second periodic dielectric multilayer film. Incident light from a polarizer passes through the periodic dielectric multilayer films, is reflected at the metal reflective film, returns through the periodic dielectric multilayer films, and passes through an analyzer to exit out.
