摘要： [Object] To provide an iron-based oxide magnetic powder, which has a sufficiently reduced content of fine particles and coarse particles, has a particle shape close to a perfect sphere, and is suitable for use in a magnetic recording medium.
[Means for Solution] A raw material solution containing trivalent iron ions, or trivalent iron ions and ions of a metal element that partially substitutes Fe sites, and an alkaline aqueous solution for neutralizing the raw material solution are added to a reaction system to adjust the pH of the reaction system to 1.0 or higher and 3.0 or lower, a hydroxycarboxylic acid is added to the obtained reaction solution and thereafter the pH of the reaction system is neutralized to 7.0 or higher and 10.0 or lower, and the obtained precipitate of a substituent metal element-containing iron oxyhydroxide is coated with silicon oxide and then heated, whereby an iron-based oxide magnetic powder which has a sufficiently reduced content of fine particles and coarse particles, has a particle shape close to a perfect sphere, and is composed of particles of ε-iron oxide in which Fe sites are partially substituted by other metal elements is obtained.

摘要： A method for cutting, separating and removing interior contoured shapes in thin substrates, particularly glass substrates. The method involves the utilization of an ultra-short pulse laser to form defect lines in the substrate that may be followed by use of a second laser beam to promote isolation of the part defined by the interior contour.

摘要： The present invention discloses a discontinuous islanded ferromagnetic recording film with perpendicular magnetic anisotropy. The discontinuous islanded ferromagnetic recording film includes a substrate and a ferromagnetic layer. The ferromagnetic layer is formed on the substrate and annealed by a high-temperature vacuum annealing process. After annealing, a surface energy difference existed between the ferromagnetic layer and the substrate turns the ferromagnetic layer into well-separated and discontinuous islanded ferromagnetic particles. Each islanded ferromagnetic particle is thought of a single magnetic domain, which is beneficial to achieve a discontinuous islanded ferromagnetic recording film with perpendicular magnetic anisotropy.
