Diffraction patterns from the SnBi alloy and Rietveld refinement fits. (Upper) Ambient pressure: β-Sn + Bi-I. (Middle) 5.8 GPa: the Cmca-oC16 phase, (partially) site-ordered. The insets show expanded views of the two low-angle peaks and of the first group of strong reflections. (Lower) 15 GPa: body-centered cubic phase, site-disordered. |
