摘要： A spin device includes: a first condenser lens which focuses a spin polarized electron beam discharged from an electron gun or reflected on a sample; a spin rotator which includes a multipole having a point to which the electron beam is focused by the first condenser lens at a lens center or in the vicinity of the lens center and being capable of generating an electric field and a magnetic field; a Wien condition generating means which applies a voltage and a current which satisfy the Wien condition for rotating spin of the electron beam by a designated angle and making the electron beam advance straightly to the multipole which constitutes the spin rotator; and a second condenser lens which focuses the electron beam whose spin is rotated by the spin rotator.
