Abstract
L3 absorption spectra of Eu in boron-containing alloys, EuPd3Bx (x=0, 0.25, 0.5, and 1.0) have been recorded. Direct evidence for the mixed-valence (Eu3+ and Eu2+) behavior of Eu in EuPd3B0.5 and EuPd3B has been provided by x-ray-absorption near-edge structure (XANES). The value of the average valence of Eu in EuPd3B and EuPd3B0.5 alloys is estimated and it is found to be temperature independent. The XANES results in conjunction with the Mossbauer measurements lead to the conclusion that EuPd3B is an inhomogeneous mixed-valence system.
