抄録
Structural properties of SmRu4P12 in the anomalous magnetic ordered phase between T* ~ 14 K and TN = 16.5 K in magnetic fields has been studied by x-ray diffraction. Atomic displacements of Ru and P, reflecting the field-induced charge order of the p electrons, have been deduced by analyzing the intensities of the forbidden Bragg peaks, assuming a cubic space groupPm¯3. Also, by utilizing a high-resolution x-ray diffraction experiment, we observed a splitting of fundamental Bragg peaks, clarifying that the unit cell in the magnetic ordered phase is rhombohedral elongated along the [1 1 1] axis. The response of the rhombohedral domains to the magnetic field, which reflects the direction of the magnetic moment, is studied in detail.
