  • Magnetic material observation method, and magnetic material observation apparatus
    Patent number: 11474169
    Abstract: A magnetic material observation method in accordance with the present invention includes: an irradiating step including irradiating a region of a sample with an excitation beam and thereby allowing a magnetic element contained in the sample to radiate a characteristic X-ray; a detecting step including detecting intensities of a right-handed circularly polarized component and a left-handed circularly polarized component contained in the characteristic X-ray; and a calculating step including calculating the difference between the intensity of the right-handed circularly polarized component and the intensity of the left-handed circularly polarized component. Reference to such a difference enables precise measurement of the direction or magnitude of magnetization without strict limitations as to the sample.
