    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: PROBLEM TO BE SOLVED: To achieve a spin polarized electron generating element having high spin polarization degree and external quantum efficiency while providing flexibility in selecting materials of a substrate, a buffer layer, and a distorted superlattice layer. SOLUTION: In the spin polarized electron generating element consisting of a substrate, a buffer layer, and a distorted superlattice layer formed on the buffer layer, an intermediate layer is interposed between the substrate and the buffer layer, the intermediate layer being made of crystal having a lattice constant larger than that of crystal constituting the buffer layer. With this, cracks in a direction perpendicular to the substrate are generated in the buffer layer due to tensile distortion, so that the buffer layer becomes mosaic-like. As a result, since a glide dislocation in an oblique direction is not introduced into the distorted superlattice layer grown on the buffer layer, the crystalline property of the distorted superlattice layer is improved. Consequently, the spin polarization degree of excited electrons and the external quantum efficiency of polarized electrons are improved. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: To provide implement a spin-polarized electron generating device having high spin polarization and high external quantum efficiency while allowing a certain degree of freedom in selecting materials of a substrate, a buffer layer, and a strained superlattice layer.
    In a spin-polarized electron generating device having a substrate, a buffer layer, and a strained superlattice layer formed on the buffer layer, an intermediate layer formed of a crystal having a lattice constant greater than that of a crystal used to form the buffer layer intervenes between the substrate and the buffer layer. With this arrangement, tensile strain causes cracks to be formed in the buffer layer in a direction perpendicular to the substrate, whereby the buffer layer has mosaic-like appearance. As a result, glide dislocations in an oblique direction do not propagate to the strained superlattice layer to be grown on the buffer layer, thereby improving crystallinity of the strained superlattice layer. Accordingly, spin polarization of excited electrons and external quantum efficiency of polarized electrons improve.
