We have succeeded for the first time in obtaining a crystal-site-selective Mössbauer spectrum of Fe3O4 using the Mössbauer diffractometer at SPring-8 BL11XU. In order to extract the nuclear resonant scattering, which provides the crystal-site-selective emission spectrum, reflections having a Bragg angle near 45° were used. The 666 and 10 10 0 re flection spectra reveal only B- and A-site spectra, respectively. Mössbauer diffraction spectroscopy enables us to measure the crystal-site-selective spectrum and to determine the precise hyperfine structure. This technique provides new possibilities for studying the local crystallographic and magnetic structure on iron sub-lattices in various multisite materials.
