Baryonic Bound State of Vortices in Multicomponent Superconductors
Baryonic Bound State of Vortices Multicomponent Superconductors
2010/11/19
We construct a bound state of three 1/3-quantized vortices in three-component su-perconductors with intrinsic Josephson couplings, which may be relevant with regard to iron-based superconductors. We f...
Symbiotic Optimization of the Nanolithography and RF-Plasma Etching for Fabricating High-Quality Light-Sensitive Superconductors on the 50 nm Scale
Symbiotic Optimization Nanolithography High-Quality Light-Sensitive Superconductors
2010/11/24
We present results of a fabrication-process development for the lithographic pattern transfer into the nm100sub range by combining electron-beam lithography and reactive dry etching to obtain ...
Here the Origin of the pseudogap in HTSC is attributed to the modulated ntiferromagnetic (AFM) phase, whose preliminary version has been sketched recently by the present author [1]. Starting from the ...

Quantum Oscillations Ferromagnetic Superconductor UCoGe
2010/11/24
We succeeded in growing high quality single crystals of the ferromagnetic superconductor
UCoGe and measured the magnetoresistance at fields up to 34T. The Shubnikov-de Haas
signal was observed for t...
On the multi-orbital band structure and itinerant magnetism of iron-based superconductors

Comparison of Graphene Formation Si-face SiC {0001} Surfaces
2010/11/19
The morphology of graphene formed on the ( 0001 ) surface (the C-face) and the (0001) surface
(the Si-face) of SiC, by annealing in ultra-high vacuum or in an argon environment, is studied by atomic ...
Possible indicators for low dimensional superconductivity in the quasi-1D carbide Sc3CoC4
Possible indicators low dimensional superconductivity quasi-1D carbide Sc3CoC4
2010/11/25
The transition metal carbide Sc3CoC4 consists of a quasi-one-dimensional (1D)structure with [CoC4]1 polyanionic chains embedded in a scandium matrix. At ambient temperatures Sc3CoC4 displays metallic ...
The effective fine structure constant of freestanding graphene measured in graphite

2010/11/18
Electrons in graphene behave like Dirac fermions, permitting phenomena from high energy
physics to be studied in a solid state setting. A key question is whether or not these Fermions are critically ...
