    摘要： A scanning magnetism detector includes a probe made of a solid material formed of a single crystal having spin polarization and electrical conductivity properties. When the probe is brought into proximity with a magnetic substance, a surface condition of the magnetic substance can be detected by measuring tunnel current flow between the probe and the surface of the magnetic substance.

    摘要： A method for producing, under a low pressure such as an ambient atmospheric pressure, a ferromagnetic chromium oxide having a sufficiently high saturation magnetization and, if necessary, sufficiently high coercive force as well. The main feature of this method is to use H.sub.2 O.sub.2 in conjunction with CrO.sub.3 and, if necessary, Te, Sb or an alkali element as well and to heat them.

    摘要： This invention provides a magnetic head constituted by a magnetic core having a winding wound thereon, the magnetic core being a ferrite body composed of crystallites which have (111)-crystallographic planes thereof oriented substantially parallel with each other. The ferrite body is a dense polycrystalline and has much improved wear characteristics. The method of manufacturing the polycrystalline ferrite body includes the steps of mixing starting materials which include an .alpha.-Fe.sub.2 O.sub.3 powder with particles having a thin disc shape and other compounds in the weight ratio of given ferrite composition, cold-pressing the mixture into a cold-pressed body by a uniaxial pressure and sintering the cold-pressed body into a solid body so that the crystallites of the sintered body have the (111) 111)-planes substantially oriented.
