Abstract: The present disclosure relates to a device and method for forming skyrmion in a magnetic thin film. A skyrmion forming method comprises aligning the surface of the magnetic thin film and a horizontal magnetic field to be applied to the magnetic thin film and applying the horizontal magnetic field and a vertical magnetic field to the magnetic thin film. Accordingly, it is possible to form the bubble skyrmion easily even in the case of a wide width of a stripe formed on the magnetic thin film.

Abstract: Provided is a method of determining a surface orientation of a single crystal wafer. The method of determining a surface orientation of a single crystal wafer using high resolution X-ray rocking curve measurement may determine a surface angle of the wafer and a direction of the surface angle using rocking curve measurement of a high resolution X-ray diffraction method and measuring a misalignment angle formed by a rotation axis of a measuring apparatus and a surface normal of the wafer and an orientation of the misalignment angle.
