Abstract: Method for transferring the Bloch line present in the magnetic wall of the magnetic domain formed in the magnetic thin film, along the magnetic wall is characterized by the steps of forming a predetermined stress distribution along the magnetic wall in the magnetic thin film, positioning the Bloch line to a predetermined position in the magnetic wall in accordance with the stress distribution, and applying a pulsive magnetic field normally to a film plane of the magnetic thin film in synchronism with the formation of the stress distribution. The Bloch line is transferred from the predetermined position to another position by the stress distribution formation step and the magnetic field application step.

Abstract: In a process or system for displacing Bloch lines, in one step only a first Bloch line of a pair of Bloch lines in a magnetic domain wall is displaced in a predetermined direction and in another step the second Bloch line of the pair of Bloch lines is displaced in the predetermined direction in order to form the pair of Bloch lines. Typically, in a first step a magnetic field perpendicular to a plane of a magnetic thin film containing the domain wall is set up at the thin film and in a second step a magnetic field parallel to the plane of the thin film is set up at the thin film along the domain wall.

Abstract: In a process or a device for determining the presence of a Bloch line in the domain wall of a magnetic domain formed in a magnetic thin film, a magnetic field is set up at the magnetic domain parallel to the plane of the magnetic thin film and induces a change in the magnetic domain, the state of which change is sensed and the presence or absence of a Bloch line at a predetermined point of the domain wall is determined from the result of this sensing.

Abstract: A magnetic record reproducing method includes the steps of bringing a magnetic film, capable of producing a magneto static wave, into intimate contact with or proximity to the recording surface of a magnetic recording medium, causing the magnetic film to produce the magnetostatic wave, detecting any variation in wave number in the magnetostatic wave attributable to the magnetized signal of the recording surface, and converting the variation in wave number in the magnetostatic wave into an electrical signal.

Abstract: In optical communications, an optical receiver or semiconductor apparatus and an optical communication system using the semiconductor apparatus of the present invention solve the problem of polarization dependency. The optical receiver or optical semiconductor apparatus includes a pair of optical filters arranged such that tuned wavelengths for two different modes, e.g., tuned wavelengths for TE and TM modes, are set as light components having the same wavelength, and a beam splitting path for directing signal light to the pair of optical filters. Alternatively, the optical receiver or optical semiconductor apparatus includes a filter waveguide or waveguides capable of setting the tuned wavelength of one mode (e.g., TE) to be the same as the tuned wavelength of the other mode (e.g., TM) of two modes having different orders of transverse modes (e.g., two orthogonal modes), and an input waveguide. The input waveguide and filter waveguide are arranged to equally couple a signal light to those two modes.
