(A = Na, Ca, and La) probed by resonant X-ray emission spectroscopyMizumaki, Masaichiro*; Mizokawa, Takashi*; Agui, Akane; Tanaka, Sotaro*; Takatsu, Hiroshi*; Yonezawa, Shingo*; Maeno, Yoshiteru*
In this study, we report the O 1
and Cu 2
X-ray absorption spectroscopy (XAS) and resonant X-ray emission spectroscopy (RXES) study on the A-site ordered perovskite ACuRuO (A = Na, Ca, and La). Hartree-Fock calculation and cluster model calculation were carried out to analyze O 1 and Cu 2 XAS spectra. The O 1 RXES spectra indicate that the number of O 2 holes increases in going from La to Ca to Na. In addition, the Cu 2 RXES spectra reveal that the charge-transfer energy decreases in going from La to Ca to Na.
