A New Noncentrosymmetric Superconducting Phase in the Li-Rh-B System
Hiroyuki Takeya, Hiroki Fujii, Mohammed ElMassalami +6
Superconductivity, at 2-3 K, was observed in a novel phase of the ternary Li-Rh-B system. The structural phase exhibits a large noncentrosymmetric cubic unit cell with the a-parame…
Structural Analysis on Iron-Based Superconductor Pr1111 System with Oxygen Deficiency and Flourine Substitution
Katsuaki Kodama, Motoyuki Ishikado, Fumitaka Esaka +3
We have performed structural analyses on iron-based superconductors, PrFeAsO and PrFeAsOF, systematically, by means of Rietveld method on neutron powder diffrac…
Possible Superconducting Symmetry and Magnetic Correlations in K0.8Fe2Se2: A 77Se-NMR Study
Hisashi Kotegawa, Yudai Hara, Hiroki Nohara +4
We report ^77Se-NMR measurements in the recent discovered K_0.8Fe_2Se_2 with the superconducting transition temperature T_c=32 K. The characteristic point of this system is that th…
Phonon, Two-Magnon and Electronic Raman Scattering of Fe1+yTe1-xSex
K. Okazaki, S. Sugai, S. Niitaka +1
We have measured Raman scattering spectra of single-crystalline FeTe0.6Se0.4 (T_c ~ 14.5 K) and its parent compound Fe1.074Te at various temperatures. In the parent compound Fe1.07…
Electronic Structure of Novel Superconductor Ca4Al2O6Fe2As2
Takashi Miyake, Taichi Kosugi, Shoji Ishibashi +1
We have performed the first-principles electronic structure calculation for the novel superconductor Ca4Al2O6Fe2As2 which has the smallest a lattice parameter and the largest As he…
Magnetotransport studies of EuFeAs: the influence of the Eu magnetic moments
Taichi Terashima, Nobuyuki Kurita, Akiko Kikkawa +4
We report resistivity and Hall effect measurements on EuFeAs at ambient pressure and 28 kbar and magnetization measurements at ambient pressure. We analyze the temperat…
