Ultrafast Spectral Weight Transfer in RBaCo2O6-delta (R=Sm, Gd, and Tb): A Role of Electronic Correlation in Photoinduced Phase Transition

Y. Okimoto, T. Miyata, M. S. Endo +8

We performed femtosecond reflection spectroscopy on a series of perovskite-type cobalt oxide $R$BaCo${}_2$O${}_{6-\delta }$ ($R$=Sm, Gd, and Tb) crystals, in which the electronic transfer wa…
