摘要： Provided herein are a device and a method for determining the spin polarization of an electron beam where the device and method contemplate diffusely back-scattering the beam from an electron opaque target, at a kinetic energy less than 10,000 electron volts, collecting the scattered electrons which may be of a preselected energy range and within a predetermined solid angle relative to the target and the collector, and measuring the number of scattered electrons which were collected.

摘要： A data recording/reproducing method, a data recording system adopting the same, and media for the system are provided. The method includes the steps of preparing media (20) having a data recording layer in which a phase change is generated through electron absorption, generating electrons using an electron generating source (40) according to data for recording at a position separated from the data recording layer by a predetermined interval, forming a magnetic field (NS) on the path of the electrons and cyclotron (50) moving the electrons, and transmitting the cyclotron moved electrons onto the data recording layer to record data through local melting and cooling due to the absorption of the electrons by the data recording layer. The micro-tip (11) does not contact the data recording layer while the electron beam collides with the data recording layer, and thus no damage is caused by waste of the micro-tip, as with a conventional AFM method, and data recording and reproduction is very fast. In addition, the electron beam is converged onto the data recording layer through cyclotron movement, and thus the region (22a) where the electron beam reaches can be minimized by properly adjusting the distance, to maximize the data recording density.

摘要： 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.
