Hydrogen-substituted superconductors SmFeAsO1-xHx misidentified as oxygen-deficient SmFeAsO1-x
Yoshinori Muraba, Soshi Iimura, Satoru Matsuishi +1
We investigated the preferred electron dopants at the oxygen sites of 1111-type SmFeAsO by changing the atmospheres around the precursor with the composition of Sm:Fe:As:O = 1:1:1:…
Narrow Bandgap in beta-BaZn2As2 and Its Chemical Origins
Zewen Xiao, Hidenori Hiramatsu, Shigenori Ueda +7
Beta-BaZn2As2 is known to be a p-type semiconductor with the layered crystal structure similar to that of LaZnAsO, leading to the expectation that beta-BaZn2As2 and LaZnAsO have si…
Quantum critical behavior in heavily doped LaFeAsOH pnictide superconductors analyzed using nuclear magnetic resonance
R. Sakurai, N. Fujiwara, N. Kawaguchi +5
We studied the quantum critical behavior of the second antiferromagnetic (AF) phase in the heavily electron-doped high- pnictide, LaFeAsOH by using As and $…
Superconductivity in Room Temperature Stable electride and high-pressure phases of alkali metals
Hideo Hosono, Sung-Wng Kim, Satoru Matsuishi +4
S-band metals such as alkali and alkaline earth metals do not undergo a superconducting transition (SCT) at an ambient pressure, but their high-pressure phases do. In contrast, roo…
Superconductivity at 52 K in hydrogen-substituted LaFeAsO1-xHx under high pressure
Hiroki Takahashi, Hideto Soeda, Muga Nukii +6
The 1111-type iron-based superconductor LnFeAsO1-xFx (Ln stands for lanthanide) is the first material with a Tc above 50 K, other than cuprate superconductors. Electron doping into…
