摘要： An apparatus for measuring an electromagnetic field distribution using a focused electron beam can measure the electromagnetic field distribution in a specimen with high resolution and high reliability. A focused electron beam radiation system irradiates a specimen with a focused electron beam. A specimen tilt mechanism tilts a specimen by 180.degree. about a tilt axis that is perpendicular to the optical axis of the focused electron beam. An electron beam position detector measures the direction and quantity of the deflection given to the focused electron beam when it is transmitted through the specimen. Further, a processing system calculates the direction and the intensity of an electric field, and the direction and the intensity of a magnetic field separately at a point on the specimen through which the focused electron beam is transmitted, from the data on the direction and the quantity of the deflection of the focused electron beam measured by the electron beam position detector before and after the turnover of the specimen by the specimen tilt mechanism. Thus, an electric field and a magnetic field in a specimen can be separately observed independently of each other.

摘要： When observing a magnetization image on a magnetic thin film by means of a scanning transmission electron microscope, the effect of a stray magnetic field is made smaller than that of a magnetization in order to produce a clear magnetic structure of the magnetization image. To relatively reduce the effect of the stray magnetic field in comparison to that of the magnetization, the scanning transmission electron microscope is equipped with a specimen-holder driving means which can rotate the surface of a specimen 5 by more than 90 degrees with an axis parallel to the optical path of an electron beam 1 taken as a center and incline the surface of the specimen 5 around a center axis 22 perpendicular to an axis 24 rotated earlier over the surface of the specimen 5 with respect to a magnetic-recording track direction and also perpendicular to the axis parallel to the optical path of the electron beam 1. In the actual observation, however, a limit is put on the angle of rotation by which the surface of the specimen 5 is rotated with respect to the recording track direction.

摘要： An electron microscope for observing a magnetization state of a specimen with high resolution and an electron microscopic method. The electron microscope comprises an electron beam irradiating device including a scanning coil 3 and an objective lens 4 to irradiate an electron beam 2 emitted from an electron source 1 on a desired part of a specimen 51, and a circularly polarized light detector including a quarter wave plate 8, a polarizer 9 and a photodetector 11 to detect circularly polarized light generated from the electron beam irradiated part of the specimen 51. Since the intensity of the circularly polarized light generated from the specimen irradiated with the electron beam depends on the direction of magnetization in the electron beam irradiated part and the detecting direction, the distribution of magnetization can be measured by observing a scanning image in the form of a luminance signal indicative of the intensity of the circularly polarized light while scanning the electron beam irradiated part on the surface of the specimen.

摘要： A charged particle beam is transmitted through a specimen for producing an irregular pattern as a first image. Further, a magnetic field to be measured is arranged in space where a charged particle beam is passed between the specimen and an image plane thereby to produce a second image having an irregular pattern as in the foregoing case. The first image and the second image are processed to produce the deflection angle of the charged particle beam due to the magnetic field. This deflection angle is extracted from the entire positions of a cross section of the space where measurement is desired, thereby constructing projection data of a magnetic field by a charged particle beam. Furthermore, the magnetic field to be measured is rotated and the above-mentioned processing is performed from each direction to construct projection data. The projection data thus obtained and the computer tomography technique are used to determine a magnetic field at each point in space.

摘要： Disclosed is a magnetic recording medium and a method for manufacturing the same to provide a magnetic recording medium reducing medium noise and having excellent thermal stability. The magnetic recording medium includes a substantially amorphous seed layer and a polycrystal underlayer made of crystal grains having a substantially columnar structure, the polycrystal underlayer contacting thereto. In a boundary between the seed layer and the underlayer, fine grooves having a period up to as large as the magnetic layer crystal grain diameter are formed in the disc circumferential direction. Accordingly, the magnetic recording medium is allowed to have a grain shape with a value obtained by dividing the average grain diameter for the disc circumferential direction by the average grain diameter for the disc radial direction of no less than 0.5 and no more than 0.9, thus achieving simultaneously reduction of the medium noise and thermal stability.
