Abstract: The present invention provides a rare earth thin film magnet having Nd, Fe, and B as essential components, wherein the rare earth thin film magnet has a texture in which an ?-Fe phase and a Nd2Fe14B phase are alternately arranged three-dimensionally, and each phase has an average crystal grain size of 10 to 30 nm. An object of this invention is to provide a rare earth thin film magnet having superior mass productivity and reproducibility and favorable magnetic properties, as well as to provide the production method thereof and a target for producing the thin film.

Abstract: A rare-earth thin film magnet is provided which includes Nd, Fe and B as essential components, characterized by including a Si substrate having an oxide film present on a surface thereof, a Nd base film formed as a first layer over the Si substrate, and a Nd—Fe—B film formed as a second layer on the first layer. The rare earth thin film magnet and a production process therefor provides a rare earth thin film magnet suffering neither film separation nor substrate breakage and having satisfactory magnetic properties even when the second layer has composition in the range of 0.120 ?Nd/(Nd+Fe)<0.150, which corresponds to a compositional range in the vicinity of a stoichiometric composition.

Abstract: Provided is a rare earth thin film magnet having Nd, Fe and B as essential components, which is characterized in that a Nd—Fe—B base film is formed on a Si substrate having an oxide film formed on a surface thereof and has a composition in which the Nd content is higher than that of a stoichiometric composition and that a film (nano composite film) is formed on the base film and has a texture in which an ?-Fe phase and Nd2Fe14B are alternately arranged and three-dimensionally dispersed. The rare earth thin film magnet provided is less susceptible to the occurrence of film separation and substrate breakage and exhibits favorable magnetic properties.

Abstract: A rare earth thin-film magnet of a Nd—Fe—B film deposited on a Si substrate, wherein, when the film thickness of the rare earth thin film is 70 ?m or less, the Nd content satisfies the conditional expression of 0.15?Nd/(Nd+Fe)?0.25 in terms of an atomic ratio; when the film thickness of the rare earth thin film is 70 ?m to 115 ?m (but excluding 70 ?m), the Nd content satisfies the conditional expression of 0.18?Nd/(Nd+Fe)?0.25 in terms of an atomic ratio; and when the film thickness of the rare earth thin film is 115 ?m to 160 ?m (but excluding 115 ?m), the Nd content satisfies the conditional expression of 0.20?Nd/(Nd+Fe)?0.25 in terms of an atomic ratio. An object of the present invention is to provide a rare earth thin-film magnet having a maximum film thickness of 160 ?m and which is free from film separation and substrate fracture, and a method of producing such a rare earth thin-film magnet by which the thin film can be stably deposited.

Abstract: A microorganism exhibiting excellent antibiotic and sterilizing properties for the preparation of medicines and the like, obtained by fusion of cells of two different fungal species. A Ganoderma and a Grifola, each exhibiting little or no antibiotic activity, are isolated and hybridized, and milled to produce a fused cell body. The cell body is black-brown, and has been deposited as deposit No. 3131 (FERM BP-3131).
