Evidence for two-gap nodeless superconductivity in SmFeAsOF from point-contact Andreev-reflection spectroscopy
D. Daghero, M. Tortello, R. S. Gonnelli +3
Point-contact Andreev-reflection measurements were performed in SmFeAsO_{0.8}F_{0.2} polycrystals with T_c \simeq 53 K. The experimental conductance curves reproducibly exhibit pea…
A Scaling Hypothesis for Modulated Systems
O. Portmann, A. Goelzer, N. Saratz +3
We propose a scaling hypothesis for pattern-forming systems in which modulation of the order parameter results from the competition between a short-ranged interaction and a long-ra…
One-dimensional Ising ferromagnet frustrated by long-range interactions at finite temperatures
F. Cinti, O. Portmann, D. Pescia +1
We consider a one-dimensional lattice of Ising-type variables where the ferromagnetic exchange interaction J between neighboring sites is frustrated by a long-ranged anti-ferromagn…
A new triclinic modification of the pyrochlore-type KOs2O6 superconductor
S. Katrych, Q. F. Gu, Z. Bukowski +3
A new modification of KOs2O6, the representative of a new structural type (Pearson symbol aP18, a=5.5668(1)A, b=6.4519(2)A, c=7.2356(2)A, space group P-1, no.2) was synthesized emp…
Charge dynamics of the spin-density-wave state in BaFeAs
F. Pfuner, J. G. Analytis, J. -H. Chu +2
We report on a thorough optical investigation of BaFeAs over a broad spectral range and as a function of temperature, focusing our attention on its spin-density-wave (SDW)…
Selection rules for Single-Chain-Magnet behavior in non-collinear Ising systems
Alessandro Vindigni, Maria Gloria Pini
The magnetic behavior of molecular Single-Chain Magnets is investigated in the framework of a one-dimensional Ising model with single spin-flip Glauber dynamics. Opportune modifica…
Pressure dependence of the single particle excitation in the charge-density-wave CeTe system
M. Lavagnini, A. Sacchetti, C. Marini +8
We present new data on the pressure dependence at 300 K of the optical reflectivity of CeTe, which undergoes a charge-density-wave (CDW) phase transition well above room temper…
Pressure-induced quenching of the charge-density-wave state observed by x-ray diffraction
A. Sacchetti, C. L. Condron, S. N. Gvasaliya +11
We report an x-ray diffraction study on the charge-density-wave (CDW) LaTe and CeTe compounds as a function of pressure. We extract the lattice constants and the CDW modula…
Oxygen-related traps in pentacene thin films: Energetic position and implications for transistor performance
Wolfgang L. Kalb, Kurt Mattenberger, Bertram Batlogg
We studied the influence of oxygen on the electronic trap states in a pentacene thin film. This was done by carrying out gated four-terminal measurements on thin-film transistors a…
Time-resolved detection of single-electron interference
S. Gustavsson, R. Leturcq, M. Studer +4
We demonstrate real-time detection of self-interfering electrons in a double quantum dot embedded in an Aharonov-Bohm interferometer, with visibility approaching unity. We use a qu…
Tunable Graphene Single Electron Transistor
C. Stampfer, E. Schurtenberger, F. Molitor +3
We report electronic transport experiments on a graphene single electron transistor. The device consists of a graphene island connected to source and drain electrodes via two narro…
Evidence for coupling between collective state and phonons in two-dimensional charge-density-wave systems
M. Lavagnini, M. Baldini, A. Sacchetti +8
We report on a Raman scattering investigation of the charge-density-wave (CDW), quasi two-dimensional rare-earth tri-tellurides Te (= La, Ce, Pr, Nd, Sm, Gd and Dy) at am…
