Infrared Measurement of the Pseudogap in P-Doped and Co-Doped BaFe2As2 High-Temperature Superconductors
S. J. Moon, A. A. Schafgans, S. Kasahara +10
We report on infrared studies of charge dynamics in a prototypical pnictide system: the BaFe2As2 family. Our experiments have identified hallmarks of the pseudogap state in the BaF…
Specific Heat Discontinuity, deltaC, at Tc in BaFe2(As0.7P0.3)2 - Consistent with Unconventional Superconductivity
J. S. Kim, G. R. Stewart, S. Kasahara +3
We report the specific heat discontinuity, deltaC/Tc, at Tc = 28.2 K of a collage of single crystals of BaFe2(As0.7P0.3)2 and compare the measured value of 38.5 mJ/molK**2 with oth…
Exotic Superconducting Properties in the Electron-Hole Compensated Heavy Fermion `Semimetal' URu2Si2
Y. Kasahara, T. Iwasawa, H. Shishido +7
We show that the charge and thermal transport measurements on ultraclean crystals of URu2Si2 reveal a number of unprecedented superconducting properties. The uniqueness is best hig…
Uncommonly High Upper Critical Field in the Superconducting KOsO Pyrochlore
T. Shibauchi, L. Krusin-Elbaum, Y. Kasahara +10
The entire temperature dependence of the upper critical field in the -pyrochlore KOsO is obtained from high-field resistivity and magnetic measurements. Bot…
Anomalous quasiparticle transport in the superconducting state of CeCoIn5
Y. Kasahara, Y. Nakajima, K. Izawa +5
We report on a study of thermal Hall conductivity k_xy in the superconducting state of CeCoIn_5. The scaling relation and the density of states of the delocalized quasiparticles, b…
Triplet superconductivity in the skutterudite PrOs_4Sb_12
Kazumi Maki, Stephan Haas, David Parker +3
There is mounting evidence for triplet superconductivity in the recently discovered skutterudite compound PrOs_4Sb_12. In this work, we propose nodal order parameters for the A- an…
