Electronic manipulation of polar order in electron crystal
Takashi Kikkawa, Ziyan Chen, Yuto Fujimoto +8
When interaction among atoms or ions is strong enough, they often arrange periodically, forming a crystal. The arrangement patterns of atoms or ions can encode information, a conce…
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 BaCoO (=Sm, Gd, and Tb) crystals, in which the electronic transfer wa…
Optical phase diagram of perovskite-type colossal magnetoresistance manganites with near-half doping
I. Kezsmarki, Y. Tomioka, S. Miyasaka +3
We present a systematic optical study for a bandwidth-controlled series of nearly half doped colossal magnetoresistive manganites REAEMnO (RE and AE being rar…
Ultrafast Photoinduced Formation of Metallic State in a Perovskite-type Manganite with Short Range Charge and Orbital Order
Yoichi Okimoto, Hiroyuki Matsuzaki, Yasuhide Tomioka +5
Femtosecond reflection spectroscopy was performed on a perovskite-type manganite, Gd0.55Sr0.45MnO3, with the short-range charge and orbital order (CO/OO). Immediately after the pho…
Anisotropy of Mott-Hubbard gap transitions due to spin and orbital ordering in LaVO3 and YVO3
Shigeki Miyasaka, Yoichi Okimoto, Yoshinori Tokura
Anisotropic optical spectra coupled with antiferromagnetic spin ordering (SO) and orbital ordering (OO) have been investigated for single crystals of LaVO_{3} and YVO_{3}. The orbi…
