Electronic and Magnetic Phase Diagram of a Superconductor, SmFeAsO1-xFx
Yoichi Kamihara, Takatoshi Nomura, Masahiro Hirano +9
A crystallographic and magnetic phase diagram of SmFeAsO1-xFx is determined as a function of x in terms of temperature based on electrical transport and magnetization, synchrotron…
Comparison of crystal structures and effects of Co substitution in a new member of Fe-1111 superconductor family AeFeAsF(Ae = Ca and Sr): a possible candidate for higher Tc superconductor
Takatoshi Nomura, Yasunori Inoue, Satoru Matsuishi +5
We refined crystal structures of newly found members of the Fe-1111 superconductor family, CaFe\_{1-x}Co\_{x}AsF and SrFe\_{1-x}Co\_{x}AsF (x = 0, 0.06, 0.12) by powder synchrotron…
Effect of 3d Transition Metal Doping on the Superconductivity in Quaternary Fluoroarsenide CaFeAsF
Satoru Matsuishi, Yasunori Inoue, Takatoshi Nomura +3
We examined doping effect of 3d transition metal elements (TM: Cr, Mn, Co, Ni, and Cu) at the Fe site of a quaternary fluoroarsenide CaFeAsF, an analogue of 1111-type parent compou…
Cobalt-substitution-induced Superconductivity in a New Compound with ZrCuSiAs-type Structure, SrFeAsF
Satoru Matsuishi, Yasunori Inoue, Takatoshi Nomura +2
We have synthesized a quaternary fluoroarsenide SrFeAsF with the ZrCuSiAs-type structure (P4/nmm, a = 0.3999 and c = 0.8973 nm), which is composed of an alternately stacked (FeAs)-…
Crystallographic Phase Transition and High-Tc Superconductivity in LaFeAsO:F
Takatoshi Nomura, Sung Wng Kim, Yoichi Kamihara +6
Undoped LaFeAsO, parent compound of the newly found high-Tc superconductor, exhibits a sharp decrease in the temperature-dependent resistivity at ~160 K. The anomaly can be suppres…
