Study of the charge and spin ordering in SrFeOx using X-ray scattering
碩士 === 淡江大學 === 物理學系碩士班 === 102 === We report the study of charge/spin-ordering in single crystal SrFeOx using resonant soft x-ray scattering. Probing the charge and spin ordering using x-rays is difficult due mainly to the very weak diffraction intensity. However, this difficulty can be overcome by...
