Local electronic structure of dilute hydrogen in -GaO probed by muons

M. Hiraishi, H. Okabe, A. Koda +6

The local electronic structure of muons (Mu) as dilute pseudo-hydrogen in single-crystalline -GaO has been studied by the muon spin rotation/relaxation (SR). High-pre…

Photoinduced Transient States of Antiferromagnetic Orderings in LaSrFeO and SrFeO Thin Films Observed through Time-resolved Resonant Soft X-ray Scattering

Kohei Yamamoto, Tomoyuki Tsuyama, Suguru Ito +12

The relationship between the magnetic interaction and photoinduced dynamics in antiferromagnetic perovskites is investigated in this study. In LaSrFeO t…

Hard x-ray photoemission study on strain effect in LaNiO thin films

K. Yamagami, K. Ikeda, A. Hariki +7

The strain effect from a substrate is an important experimental route to control electronic and magnetic properties in transition-metal oxide (TMO) thin films. Using hard x-ray pho…

Crystal structure built from a GeO-GeO polyhedra network with high thermal stability: -SrGeO

Christian A. Niedermeier, Jun-ichi Yamaura, Jiazhen Wu +4

By tackling the challenge of extending transparent oxide semiconductors to Ge based oxides, we have found a not-yet-reported crystal structure, named -SrGeO, which is co…

Shallow Valence Band of Rutile GeO and P-type Doping

Christian A. Niedermeier, Keisuke Ide, Takayoshi Katase +2

GeO has an -quartz-type crystal structure with a very wide fundamental band gap of 6.6 eV and is a good insulator. Here we find that the stable rutile-GeO polymorph with…

Particulate Generation on Surface of Iron Selenide Films by Air Exposure

Hidenori Hiramatsu, Kota Hanzawa, Toshio Kamiya +1

Nanometer-sized particular structures are generated on the surfaces of FeSe epitaxial films directly after exposure to air; this phenomenon was studied in the current work because…
