Neutron diffraction study on phase transition and thermal expansion of SrFeAsF
Y. Xiao, Y. Su, R. Mittal +9
The magnetic ordering and crystal structure of iron pnictide SrFeAsF was investigated by using neutron powder diffraction method. With decreasing temperature, the tetragonal to ort…
Two-Dimensional Spin Dynamics in the Itinerant Ferromagnet LaCoPO Revealed by Magnetization and P-NMR Measurements
Hitoshi Sugawara, Kenji Ishida, Yusuke Nakai +5
We have performed magnetization and P-NMR measurements on the itinerant ferromagnet LaCoPO (Curie temperature K) with a layered structure in order to…
Origin of critical-temperature enhancement of an iron-based high-T_c superconductor, LaFeAsO_{1-x}F_{x} : NMR study under high pressure
T. Nakano, N. Fujiwara, K. Tatsumi +5
Nuclear magnetic resonance (NMR) measurements of an iron (Fe)-based superconductor LaFeAsO_{1-x}F_x (x = 0.08 and 0.14) were performed at ambient pressure and under pressure. The r…
Atomically-flat, chemically-stable, superconducting epitaxial thin film of iron-based superconductor, cobalt-doped BaFeAs
Takayoshi Katase, Hidenori Hiramatsu, Hiroshi Yanagi +3
Epitaxial growth of Fe-based superconductors such as Co-doped SrFeAs (SrFeAs:Co) was reported recently, but has still insufficient properties for device application…
To What Extent Iron-Pnictide New Superconductors Have Been Clarified: A Progress Report
Kenji Ishida, Yusuke Nakai, Hideo Hosono
In this review, the authors present a summary of experimental reports on newly discovered iron-based superconductors as they were known at the end of 2008. At the same time, this p…
Water-induced superconductivity in SrFe2As2
Hidenori Hiramatsu, Takayoshi Katase, Toshio Kamiya +2
It has been considered that FeAs-based high transition temperature (high-Tc) superconductors need electron or hole doping by aliovalent ion substitution or large off-stoichiometry…
