Abstract
A diamond spin sensor includes a diamond substrate and an inclined surface formed on the diamond substrate. Color centers with electron spin are formed on the inclined surface. Among the color centers formed on the inclined surface, color centers with a color center axis perpendicular to the inclined are present in a proportion twice or more color centers with a color center axis not perpendicular to the inclined surface.
