Etch-Pit Patterns and Crystal Structure of PtSb2

Abstract

The lack of fourfold symmetry about the 〈100〉 axes of PtSb₂ (cubic class T_h) is revealed by a simple etching technique. The relative intensities of the 102 and 012 spots in a Laue back reflection pattern for a (001) surface are correlated with the etch‐pit pattern.
