Superconductivity in an Orbital-reoriented SnAs Square Lattice: a Case Study of Li0.6Sn2As2 and NaSnAs

Junjie Wang, Tianping Ying, Jun Deng +14

Searching for functional square lattices in layered superconductor systems offers an explicit clue to modify the electron behavior and find exotic properties. The trigonal SnAs3 st…

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…
