“…As a second example, site occupation of indium in Zr 2 Rh was based on observed EFG symmetries. The two EFGs observed had ω Q = 13 Mrad/s with η = 0 and ω Q = 11 Mrad/s and η = 0.93, which correspond to probes on the Rh-site (with 6m2 site symmetry) and on the Zr site (with mm symmetry) respectively [61]. Other examples include indium site occupation in the HfAl 2 and ZrAl 2 Laves phases [62], and indium and hafnium in bixbyites [63,64].…”
