From: Pressure-induced anomalous valence crossover in cubic YbCu5-based compounds
The experimental results of Yb2Pd2Sn are shown. (a) Temperature dependence of the PFY-XAS spectra at ambient pressure. Arrows in (a) correspond to the direction to decrease the temperature. (b) Temperature dependence of the Yb valence estimated from the fits to the PFY-XAS spectra (closed circle) and the RXES spectra (open square) at hv = 8938 eV. (c) Pressure dependence of the PFY-XAS spectra at 20 K. (d) Pressure dependence of the Yb valence estimated from the fits to the PFY-XAS spectra (closed circle) and the RXES spectra (open square). In (d) we also show the pressure dependence of the Néel temperature as a yellow-colored area, where the data are taken from the literature16. (e) Crystal structure of Yb2Pd2Sn.
