(a) The mean isotropic displacement as a function of temperature for the three host sites, along with the fitted Debye model and resulting ΘD for each host structure site. The trend of ΘD(16i) > ΘD(24k) > ΘD(6c) agrees with preferential occupation of 6c by Au and small amount on 24k. (b) The different bond lengths in the host structure as a function of temperature. |
