Strange Inter-layer Properties of Appearing in Ultrasonic Measurements
S. Simayi, K. Sakano, H. Takezawa +9
We have investigated the elastic constant C33 of Ba(Fe1-xCox)2As2 with eight different Co concentrations by ultrasonic measurement. We found remarkable elastic anomalies near the q…
Universality of dispersive spin-resonance mode in superconducting BaFe2As2
C. H. Lee, P. Steffens, N. Qureshi +5
Spin fluctuations in superconducting BaFe2(As1-xPx)2 (x=0.34, Tc = 29.5 K) are studied using inelastic neutron scattering. Well-defined commensurate magnetic signals are observed a…
Strong electronic correlations in iron pnictides: Comparison of the optical spectra for BaFe2As2-related compounds
M. Nakajima, S. Ishida, T. Tanaka +11
We carried out combined transport and optical measurements for BaFe2As2 and five isostructural transition-metal (TM) pnictides. The low-energy optical conductivity spectra of these…
Effects of Zn substitution on the electronic structure of BaFeAs revealed by angle-resolved photoemission spectroscopy
S. Ideta, T. Yoshida, M. Nakajima +13
In Fe-based superconductors, electron doping is often realized by the substitution of transition-metal atoms for Fe. In order to investigate how the electronic structure of the par…
Effect of doping on the magnetostructural ordered phase of iron arsenides: A comparative study of the resistivity anisotropy in the doped BaFeAs with doping into three different sites
Shigeyuki Ishida, Masamichi Nakajima, Tian Liang +8
In order to unravel a role of doping in the iron-based superconductors, we investigated the in-plane resistivity for BaFeAs doped at either of the three different lattice s…
Pseudogap formation above the superconducting dome in iron-pnictides
T. Shimojima, T. Sonobe, W. Malaeb +29
The nature of the pseudogap in high transition temperature (high-Tc) superconducting cuprates has been a major issue in condensed matter physics. It is still unclear whether the hi…
