Thermodynamic Study of Nodal Structure and Multiband Superconductivity of KFe2As2
Shunichiro Kittaka, Yuya Aoki, Naoki Kase +12
The temperature, field, and field-orientation dependences of the electronic specific heat Ce of the ironpnictide superconductor KFe2As2 have been investigated. Thermodynamic eviden…
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…
Normal-state charge dynamics in doped BaFe2As2: Roles of doping and necessary ingredients for superconductivity
M. Nakajima, S. Ishida, T. Tanaka +11
We carried out a comparative study of the in-plane resistivity and optical spectrum of doped BaFe2As2 and investigated the doping evolution of the charge dynamics. For BaFe2As2, ch…
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…
Superconducting gap with sign reversal between hole pockets in heavily hole-doped Ba1-xKxFe2As2
D. Watanabe, T. Yamashita, Y. Kawamoto +16
To gain insight into the unconventional superconductivity of Fe-pnictides with no electron pockets, we measure the thermal conductivity and penetration depth in the heavily…
