摘要： Method for producing a doped dilute ferromagnetic semiconductor material, by doping Zinc Oxide in bulk form with Manganese to a maximum level of 5 atomic percent concentration. The material is preferably sintered at a maximum temperature of 650 °C. The result of this process is a semiconductor material comprising Mn-doped ZnO with a Mn concentration not exceeding 5 at%, wherein said Mn-doped ZnO is ferromagnetic within at least a part of the temperature range from about 218 Kelvin to about 425 Kelvin.

摘要： A magnetic sensor provided with a head including an amorphous magnetic member whose effective length Leff is constant independently of its soldering state. The amorphous magnetic member (1) includes electrodes (7) formed of nonmagnetic conductor coating on both ends and has an effective length Less of magnetic field detection, and the magnetic member is provided in the head (10) of a magnetic sensor (100). The electrode gap Lco of the amorphous magnetic member (1) can be defined with an allowance of several microns by applying nonmagnetic conductor coating, and the effective length Leff of the amorphous magnetic member (1) can be defined with an allowance of several microns. As a result, measurement accuracy of the magnetic sensor can be improved independently of the state of a solder (2).

摘要： The present invention provides a soft magnetic thin film having high reliability that is useful in a magnetic device such as a magnetic head, where the degradation of heat stability due to a high saturation magnetic flux density of the soft magnetic thin film, the degradation of resistance against surroundings and substrate breakage are suppressed. The magnetic thin film of the present invention comprises a magnetic film comprising approximately columnar, needle or branched magnetic crystal grains as a mother phase, which is formed by sputtering or the like. The magnetic crystal grains have an average maximum length more than 50 nm, and an average crystal size in a short direction of the approximately columnar or needle shape is more than 5 nm and less than 60 nm.

摘要： A magnetic apparatus includes a magnetic semiconductor thin film (2), a power source (7) for generating an electric field, an electrode (4) for supplying charge from the power source (7) to the magnetic thin film (2), a polarizer (5) for linearly polarizing light emitted on the magnetic semiconductor thin film in a specific direction, and an analyzer (6) for transmitting polarized light when the polarized light upon transmission through the magnetic semiconductor thin film (2) has a specific Faraday rotational angle. When the electric field is applied to the magnetic semiconductor thin film, the magnetic order-disorder transition temperature of the film (2) is changed to change a Faraday rotational angle. The light (L) is transmitted through or shielded by the analyzer (6) in correspondence with the Faraday rotational angle.

摘要： This invention relates to a thin film of an amorphous magnetic material including ion-nitride having the formula FexNi-x, where x is from 0.4 to 0.7. The film is deposited on a substrate by sputter deposition in the presence of an inert gas and at a pressure from 25µm to 100µm. The coercivity of the magnetic material varies as a function of the gas pressure employed during sputtering.
