Abstract

A magnetic measurement system includes an X-ray source, a monochromator that converts right- and left-polarization X-ray into right- and left-monochromatic X-ray, an aperture slit that allows the right- and left-monochromatic X-ray to pass through, an analytical section, and piezoelectric scanning devices. The analytical section has a Fresnel zone plate that receives and focuses the right- and left-monochromatic X-ray on a single point being 10 nm or less wide of a magnetic sample, an order-sorting aperture that allows the focused X-ray to selectively pass through, a sample-stage that sets a comparatively thick magnetic sample that is more than 150 nm thick and less than or equal to 1000 nm thick to be irradiated with the X-ray, and an X-ray-detector that detects transmittance of transmission X-ray passing through the comparatively thick sample and that generates X-ray magnetic circular dichroism (XMCD) data by directly measuring the detected transmittance of the transmission X-ray.
