(a) Photograph of the patterned sample, taken using a metallurgical microscope. The micro-dot patterns made of permalloy (Ni81Fe19) were fabricated on the silicon substrate. (b) The SX-induced fluorescence spectra recorded inside the micro-dot (red-curve, point B) and outside the micro-dot (blue-curve, point A). (c) Element-specific two-dimensional mapping measured by counting the number of Fe Lα X-rays. |
