Superconductivity-induced optical anomaly in an iron arsenide
A. Charnukha, P. Popovich, Y. Matiks +5
One of the central tenets of conventional theories of superconductivity, including most models proposed for the recently discovered iron-pnictide superconductors, is the notion tha…
Specific heat of Ba0.68K0.32Fe2As2: evidence for multiband strong-coupling superconductivity
P. Popovich, A. V. Boris, O. V. Dolgov +5
The specific heat of high-purity single crystals with the highest reported superconducting = 38.5 K was studied. The electronic specific heat,…
Iron pnictides: Single crystal growth and effect of doping on structural, transport and magnetic properties
G. L. Sun, D. L. Sun, M. Konuma +6
We demonstrate the preparation of large, free standing iron pnictide single crystals with a size up to 20 x 10 x 1 mm3 using solvents in zirconia crucibles under argon atmosphere.…
Signatures of Electronic Correlations in Optical Properties of LaFeAsOF
A. V. Boris, N. N. Kovaleva, S. S. A. Seo +5
Spectroscopic ellipsometry is used to determine the dielectric function of the superconducting LaFeAsOF ( = 27 K) and undoped LaFeAsO polycrystalline samples i…
Superconductivity mediated by a soft phonon mode: specific heat, resistivity, thermal expansion and magnetization of YB6
R. Lortz, Y. Wang, U. Tutsch +7
The superconductor YB6 has the second highest critical temperature Tc among the boride family MBn. We report measurements of the specific heat, resistivity, magnetic susceptibility…
