Figure 6
The powder diffraction patterns and secondary electron images for Tm2.22Co6Sn20, (I), and TmLi2Co6Sn20, (II). An enlargement of the angular range 36.4 < 2θ < 46.4 is given in the inset on the right-hand side, showing the differences between the intensities of some reflections of phases (I) and (II). The smaller insets show scanning electron microscopy (SEM) images of the alloy samples. |
