Magnetic material observation method, and magnetic material observation apparatus

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.

Method of examining a sample using a charged particle microscope

The invention relates to a method of examining a sample using a charged particle microscope, comprising the steps of providing a charged particle beam, as well as a sample; scanning said charged particle beam over said sample; and detecting, using a first detector, emissions of a first type from the sample in response to the beam scanned over the sample. Spectral information of detected emissions of the first type is used for assigning a plurality of mutually different phases to said sample. In a further step, a corresponding plurality of different color hues—with reference to an HSV color space—are associated to said plurality of mutually different phases. Using a second detector, emissions of a second type from the sample in response to the beam scanned over the sample are detected. Finally an image representation of said sample is provided.
