【 摘 要 】

Measurements of core and valence electronic states of single crystals of the rare earth transition metal Zintl phases Yb(sub 14)MnSb(sub 11) and Yb(sub 14)ZnSb(sub 11) were performed using the X-ray photoelectron spectroscopy station of Beamline 7 at the Advanced Light Source. Sample surfaces of Yb(sub 14)MnSb(sub 11) and Yb(sub 14)ZnSb(sub 11) were measured as received, after Ar(sup +) ion bombardment, and after cleaving in situ. Detailed analysis of the clean Mn and Zn analog sample surfaces reveal a significant contribution of both Yb(sup 3+) and Yb(sup 2+) 4f states in the valence band region for the Zn analog and no contribution of Yb(sup 3+) states to the valence band for the Mn analog.
