    Abstract: A data storage device including a substrate, a data storage layer on the substrate, and a spin-polarized electron source. The data storage layer comprises a fixed number of atomic layers of a magnetic material which provide the data storage layer with a magnetic anisotropy perpendicular to a surface of the data storage layer. A data magnetic field is created in the data storage layer. The data magnetic field is polarized either in a first direction corresponding to a first data value or in a second direction corresponding to a second data value. Data is stored in the data storage layer by providing a spin-polarized electron having an electron magnetic field with a direction of polarization corresponding to one of the first and the second data values, the electron having a wavelength 'characteristic' of unpaired electrons in the data storage layer which cause the magnetic moment of the material, and directing the spin-polarized electron at the data magnetic field to impart the direction of polarization of the electron magnetic field to the data magnetic field. Data is read from the data storage layer by directing the spin-polarized electron at a second wavelength at the data magnetic field and detecting a deflection or attraction of the spin-polarized electron by the data magnetic field. Alternatively, data is read from the data storage layer by directing the spin-polarized electron at the data magnetic field so that the magnetic medium produces a secondary electron and then detecting certain characteristics of the secondary electron.

    Abstract: An electron emitting element (10) including a semiconductor opto-electronic layer (18) having a split valence band and capable of emitting a beam of spin-polarized electrons from an emitting surface (19) thereof upon incidence of an excitation laser radiation upon the emitting surface, and a reflecting mirror (14) formed on one of opposite sides of the opto-electronic layer remote from the emitting surface and cooperating with the emitting surface to effect multiple reflection therebetween of the incident laser radiation. The emitting element may be provided with a semiconductor light modulator element (114, 150, 170, 216, 280, 298) for modulating the intensity of the laser radiation incident upon the opto-electronic layer. A laser source (212, 304) may be formed integrally with the emitting element and disposed on the side of the opto-electronic layer remote from the emitting surface.

    Abstract: Apparatus for spin polarizing a particle beam, which is adapted to process an input particle beam (Bi) in such a way as to generate an at least partially spin polarized output particle beam (Bo), and comprises:
    - a vortex beam generator (1) for imparting orbital angular momentum to the input particle beam;
    - an electromagnetic field generator (5) for generating a transverse magnetic field, space-variant and symmetric with respect to the (z) axis of the input particle beam, in such a way as to change the spin of the particles and attach thereto a plurality of different values of orbital angular momentum in dependence on their input spin values; and
    - a beam component separating group (7, 9) for spatially separating the particles in dependence on their orbital angular momentum values, in such a way as to obtain the at least partially spin polarized output particle beam.
