摘要： A composite ferrite cloth having ferro-magnetic property weaved with composite ferrite textile has been found. The composite ferrite textile is the mixture of ferrite powder and the binder for coupling the same. The binder may be a high molecule compound like plastics, or glass with low melting point. The composite textile may be produced either by slicing a composite ferrite sheet attached on a plastics substrate, depositing composite ferrite paint around a core textile similar to the producing process of an electric wire, or just mixing ferrite powder with plastics or glass. The ferrite cloth which is weaved with composite ferrite textile is flexible and has many fields of application.

摘要： A magneto-optic element is employed to create an optical attenuator, an optical modulator and a magnetic field strength sensor. The magneto-optic element exhibits a multiple domain structure in a state where no magnetic field is applied, wherein magnetization components in adjacent domains of the element along a direction in which a light beam travels are different from one another. The optical attenuator further includes apparatus for applying a magnetic field of variable strength to the magneto-optic element. The optical modulator further includes apparatus for applying a modulated magnetic field to the magneto-optic element. The magnetic field strength sensor operates by placing the magneto-optic element in the vicinity of an object to be measured. A light beam is directed from an input optical fiber onto the magneto-optic element and the element diffracts the light beam. A portion of the light beam exiting the element impinges on a reflector and is received by a second optical fiber. In the optical attenuator, that portion of light is attenuated with respect to the light in the input optical fiber. In the optical modulator, that portion of light is modulated with respect to the light in the input optical fiber. In the magnetic field strength sensor, that portion of light is representative of the magnetic field of the object in the vicinity of the magneto-optic element.

摘要： A magnetic multilayer is an alternate stack of a plurality of magnetic thin films containing Fe, Co or Ni and a plurality of Ag thin film. Both the films are formed by molecular beam epitaxy to a thickness of 2 to 60 .ANG.. The multilayer has an axis of easy magnetization in a plane parallel to the surface and an in-plane squareness ratio of 0.5 or lower and exhibits antiferromagnetism. The multilayer shows giant magnetoresistance change in low magnetic fields, for example, a magnetoresistance change of 1 to 40% in a magnetic field of 0.01 to 20 kOe.

A material of at least one layer of at least either zones is birefringent, and the birefringent layer is formed by oblique vapor deposition. The polarizer, excellently suited for quantity production and for space and size reduction, can be formed directly and simply on the planes of light beam incidence or emergence of various optical elements. The invention also concerns polarizer-equipped optical elements and a method of manufacturing such elements which have the polarizer directly formed by oblique deposition on the plane of light beam incidence, emergence, or reflection of the optical elements.
