Controlling Factors of Tc-Dome Structure in 1111-Type Iron Arsenide Superconductors
Satoru Matsuishi, Takuya Maruyama, Soshi Iimura +1
We investigated the effects of phosphorus substitution on the shape of the Tc(x) dome in 1111-type SmFeAs1-yPyO1-xHx (0 < x < 0.5). Hydride ion substitution of oxide sites (O2- ->…
Enhancing the three-dimensional electronic structure in 1111-type iron arsenide superconductors by H-substitution
Yoshinori Muraba, Satoru Matsuishi, Hideo Hosono
The 1111-type iron arsenide hydride CaFe1-xCoxAsH was synthesized by high-pressure solid-state reaction, and its electronic structure and superconducting properties were investigat…
Epitaxial Growth and Electronic Structure of a Layered Zinc Pnictide Semiconductor, beta-BaZn2As2
Zewen Xiao, Fan-Yong Ran, Hidenori Hiramatsu +3
BaZn2As2 is expected for a good p-type semiconductor and has two crystalline phases of an orthorhombic alpha phase and a higher-symmetry tetragonal beta phase. Here, we report high…
Model of the Electronic Structure of Electron-Doped Iron-Based Superconductors: Evidence for Enhanced Spin Fluctuations by Diagonal Electron Hopping
Katsuhiro Suzuki, Hidetomo Usui, Soshi Iimura +4
We present a theoretical understanding of the superconducting phase diagram of the electron-doped iron pnictides. We show that, besides the Fermi surface nesting, a peculiar motion…
Detection of antiferromagnetic ordering in heavily doped LaFeAsO1-xHx pnictide superconductors using nuclear-magnetic-resonance techniques
N. Fujiwara, S. Tsutsumi, S. Iimura +4
We studied double superconducting (SC) domes in LaFeAsO1-xHx by using 75As- and 1H-nuclear magnetic resonance techniques, and unexpectedly discovered that a new antiferromagnetic (…
Switching of intra-orbital spin excitations in electron-doped iron pnictide superconductors
Soshi Iimura, Satoru Matsuishi, Masashi Miyakawa +10
We investigate the doping dependence of the magnetic excitations in two-superconducting-dome-system LaFeAsO1-xDx. Using inelastic neutron scattering, spin fluctuations at different…
