Magnetism driven by strong electronic correlation in the heavily carrier-doped iron oxypnictide LaFeAsOH
M. Hiraishi, K. M. Kojima, H. Okabe +7
The magnetism of the second antiferromagnetic phase (AF2) arising in the iron-based LaFeAsOH superconductor for was investigated by muon spin rotation m…
Higher-Order Topological Crystalline Insulating Phase and Quantized Hinge Charge in Topological Electride Apatite
Motoaki Hirayama, Ryo Takahashi, Satoru Matsuishi +2
In higher-order topological insulators, bulk and surface electronic states are gapped, while there appear gapless hinge states protected by spatial symmetry. Here we show by ab ini…
Electronic structure of interstitial hydrogen in In-Ga-Zn-O semiconductor simulated by muon
K. M. Kojima, M. Hiraishi, H. Okabe +7
We report on the local electronic structure of interstitial muon (Mu) as pseudo-hydrogen in In-Ga-Zn oxide (IGZO) semiconductor studied by muon spin rotation/relaxation (SR) exp…
Quantum dynamics of hydrogen in iron-based superconductor LaFeAsO0.9D0.1 measured with inelastic neutron spectroscopy
Jun-ichi Yamaura, Haruhiro Hiraka, Soshi Iimura +13
Inelastic neutron scattering was performed for an iron-based superconductor LaFeAsO0.9D0.1, where most of D (deuterium) replaces oxygen, while a tiny amount goes into interstitial…
Pressure-induced quantum critical point in a heavily hydrogen-doped iron-based superconductor LaFeAsO
Masayoshi Takeuchi, Naoki Fujiwara, Takanori Kuwayama +6
An iron-based superconductor LaFeAsOH (0 0.6) undergoes two antiferromagnetic (AF) phases upon H doping. We investigated the second AF phase (=0.6) usi…
Insulator-like behavior coexisting with metallic electronic structure in strained FeSe thin films grown by molecular beam epitaxy
Kota Hanzawa, Yuta Yamaguchi, Yukiko Obata +4
This paper reports that ~10-nm-thick FeSe thin films exhibit insulator-like behavior in terms of the temperature dependence of their electrical resistivity even though bulk FeSe ha…
