Abstract: Provided is a method of measuring a magnitude of magnetization of a perpendicular magnetic thin film, including: forming a stripe pattern in which a first magnetic domain that extends in a y direction and is magnetized in a z direction and a second magnetic domain that extends in the y direction and is magnetized in a direction opposite to the z direction are arranged alternately in an x direction, in a perpendicular magnetic thin film that extends in an xy plane; changing widths in the x direction, of the first and second magnetic domains by applying a magnetic field having a predetermined magnitude, in the z direction, to the perpendicular magnetic thin film; and calculating an absolute value of the magnetization of the perpendicular magnetic thin film on the basis of a ratio between the widths in the x direction, of the first magnetic domain and the second magnetic domain.

Abstract: Disclosed are a multi-mode thermal imaging device and an operation method thereof. According to an embodiment of the present invention, in a first mode, a first sample is scanned with an optical signal from a light source, signals reflected from the first sample by the scanning are detected separately for each wavelength, a reflectance change spectrum according to the wavelength is derived on the basis of the signals detected separately for each wavelength, a wavelength is selected on the basis of the derived reflectance change spectrum, and a thermal image of the first sample is obtained, through a filter, by detecting an optical signal limited to the selected wavelength from among the signals reflected from the first sample. In a second mode, thermal radiation of a second sample is detected to obtain a thermal image of the second sample.

Abstract: The present invention relates to a three-dimensional cell culture container. A cell culture container according to the present invention may include: a barrier part composed of two or more pillars (110) provided on the top side of the lower plate; an upper plate (130) which finishes an opened end portion of the barrier part; and one or more cell sample injection guide parts (220) provided in one side of the upper plate. The present invention using such configurations can stably inject a sample including cells into an accurate position in a state that the sample leans on the guide parts, and the inlet guide may perform a barrier function such that a flow of the sample is directed toward the culture container, and the upper plate and the plurality of pillars facilitate an operation of an experimenter by performing a helping function such that an appropriate amount of sample is injected easily and uniformly, while the pillar parts spaced apart from one another at predetermined intervals enable a stable cell culturing process to be performed by performing a barrier function of preventing a gel-type sample from being discharged to the outside and performing a function of opening a space for exchanging materials with a medium in an external cell.

Abstract: An atomic layer polishing method is described. The method includes: scanning the surface of a specimen to measure a peak site on the specimen surface; spraying toward the measured peak site a gas containing an element capable of binding to a first atom, which is an ingredient of the material of the specimen to form a first reaction gas layer in which the first reaction gas binds to the first atom on the surface of the peak; and projecting ions of inert gas to the peak site on which the first reaction gas layer is deposited to separate the first atom bound to the first reaction gas from the specimen.
