Figure 3
(a) Temperature dependence of the g parameter at the 4(b) site of the metastable NaCl-type structure; (b) temperature dependence of mean volume per single atom. Open and black filled squares show the metastable and stable phases, respectively. For data without error bars, estimated errors are smaller than the marks. The two lines in the figure were obtained by the least-squares method for each phase using the data except for those indicated by arrows. |
