Theoretical Investigation of Optical Conductivity in Ba [Fe(1-x)Co(x)]2 As2
A. Sanna, F. Bernardini, G. Profeta +6
We report on theoretical calculations of the optical conductivity of Ba [Fe(1-x)Co(x)]2 As2, as obtained from density functional theory within the full potential LAPW method. A tho…
Nanoscopic coexistence of magnetic and superconducting states within the FeAs layers of CeFeAsO1-xFx
S. Sanna, R. De Renzi, T. Shiroka +8
We report on the coexistence of magnetic and superconducting states in CeFeAsO1-xFx for x=0.06(2), characterized by transition temperatures T_m=30 K and T_c=18 K, respectively. Zer…
Th substituted SmFeAsO: structural details and superconductivity with Tc above 50 K
N. D. Zhigadlo, S. Katrych, S. Weyeneth +6
Superconducting poly- and single-crystalline samples of Sm1-xThxFeAsO with partial substitution of Sm3+ by Th4+ were synthesized and grown under high pressure and their structural,…
Andreev and Single Particle Tunneling Spectroscopies in Underdoped Cuprates
Kai-Yu Yang, Kun Huang, Wei-Qiang Chen +2
We study tunneling spectroscopy between a normal metal and underdoped cuprate superconductor modeled by a phenomenological theory in which the pseudogap is a precursor to the undop…
Inelastic x-ray scattering investigations of lattice dynamics in SmFeAsOF superconductors
M. Le Tacon, T. R. Forrest, Ch. Rüegg +10
We report measurements of the phonon density of states as measured with inelastic x-ray scattering in SmFeAsOF powders. An unexpected strong renormalization of phonon b…
2D orbital-like magnetic order in
V. Balédent, B. Fauqué, Y. Sidis +6
In high temperature copper oxides superconductors, a novel magnetic order associated with the pseudogap phase has been identified in two different cuprate families over a wide regi…
