Abstract

s law and the spectroscopically determined values of the valences of Ce and Yb as a function of [GRAPHICS] to determine the actual composition [GRAPHICS] of bulk single crystals. This analysis is supported by energy-dispersive X-ray spectroscopy, wavelength-dispersive X-ray spectroscopy, and transmission X-ray absorption edge spectroscopy measurements. The actual composition [GRAPHICS] is found to be about one-third of the nominal concentration [GRAPHICS] up to [GRAPHICS] [GRAPHICS] 0.5, and resolves the discrepancy between the variation of the physical properties of [GRAPHICS] single crystals and thin films with Yb concentration.
