摘要： The magnetization state of a ferromagnetic material is controlled by applying a current pulse to it while externally applying a weak magnetic field to it. The magnetic state of a ferromagnetic material can be switched between a uniformly magnetized state and a multiple magnetic domain structure by controlling the direction and intensity of the magnetic field applied to it and the intensity and pulse width of the current pulse. When an external magnetic field is applied, the possibility of occurrence of the reversal of the magnetic state upon application of the current pulse shows a hysteresis, and the reversal of the magnetic state can be controlled reliably. The intensity of the magnetic field to be applied may be as weak as a few gauss. Furthermore, by using such magnetic information recording elements, a magnetic information recording device (memory) that can achieve a high degree of integration can be produced.

摘要： A double-biprism electron interferometer is an optical system which dramatically increases the degree of freedom of a conventional one-stage electron interferometer. The double-biprism electron interferometer, however, is the same as the optical system of the single electron biprism interferometer in terms of the one-dimensional shape of an electron hologram formed by filament electrodes, the direction of an interference area and the azimuth of the interference fringes. In other words, the longitudinal direction of the interference area is determined corresponding to the direction of the filament electrodes, and the azimuth of the interference fringes only coincides with and is in parallel with the longitudinal direction of the interference area.An interferometer according to the present invention has upper-stage, intermediate-stage, and lower-stage electron biprisms, operates with an azimuth angle Φ among filament electrodes of the three electron biprisms to arbitrarily control an interference area and an azimuth θ of the interference fringes formed therein, eliminates Fresnel fringes generation, and allows independent control of an interference fringe spacing s and the azimuth θ of the interference fringes.

摘要： Although, conventionally, there were two methods, (1) a wave was transmitted through a spiral phase plate and (2) a diffraction grating containing an edge dislocation was used, they incurred complication of a configuration and securement of a larger amount of space and were not efficient because each of the spiral wave generation methods needed an incident wave to be a plane wave and at least one time of imaging is necessary at the time of wave irradiation on an observation object. In order to efficiently generate the spiral wave having a sufficient intensity, a structure of edge dislocation is taken in into a pattern of the zone plate and a spiral pattern containing a discontinuous zone is formed. Moreover, a thickness and a quality of material that change the phase of the wave by an odd multiple of π are selected for a material of the wave-blocking section in the pattern.

摘要： In an electron beam interference system using an electron biprism, which is capable of independently controlling each of the interference fringe spacing s and the interference width W, both of which are important parameters for an interferometer and for an interferogram acquired by the interferometer, an optical system used in a two-stage electron biprism interferometer is adopted. The optical system uses two stages of electron biprisms in an optical axis direction to give the flexibility to the relative magnification relative to a specimen image and that relative to an image of a filament electrode of the electron biprism. In addition, as a two-stage configuration in which two objective lenses (51, 52) are combined, independently controlling the focal length of each objective lens makes it possible to set the relative magnification relative to a specimen image and that relative to an image of the filament electrode of the electron biprism at arbitrary values.

摘要： Charged particle beam equipment having a rotary mechanism in which shift of the observing/machining position incident to the rotary operation of the equipment having the rotary mechanism can be corrected conveniently with high precision in a plane perpendicular to the optical axis of the optical system of charged particle beam or in a slightly inclining plane. An X-Y shift incident to rotation in a plane is determined from the angular information of a rotary mechanism such as a sample holder, diaphragms or biprisms in the charged particle beam equipment, and then driving or controlling is performed to cancel the X-Y shift.
