Local Density of States in Superconductor - Ferromagnetic Hybrid Systems
In this Letter we discuss various properties of the local density of states (DOS) for a superconductor-ferromagnet hybrid system. The DOS is modified at small energies on both sides of the interface. Due to the interplay of superconductivity and ferromagnetism, the local DOS depends on the spin direction. The spin polarization effects extend over a long distance from the interface both in the s...
متن کاملElectronic correlations in the superconductor LaFeAsO0.89F0.11 with low carrier density
The crystal structure and numerous normal and superconducting state properties of layered tetragonal P4 /nmm LaFeAsO, with F doping of 11%, are reported. Resistivity measurements give an onset transition temperature Tc=28.2 K, and low field magnetic susceptibility data indicate bulk superconductivity. In applied magnetic field, analysis of the resistive transition results in a critical field Hc...
متن کاملBipolaron density-wave driven by antiferromagnetic correlations and frustration in organic superconductors
We describe the paired electron crystal (PEC) which occurs in the interacting frustrated twodimensional 4filled band. The PEC is a charge-ordered state with nearest-neighbor spin singlets separated by pairs of vacant sites, and can be thought of as a bipolaron density wave. The PEC has been experimentally observed in the insulating state proximate to superconductivity in the organic chargetrans...
متن کاملLocal density of states in a dirty normal metal connected to a superconductor.
A superconductor in contact with a normal metal not only induces superconducting correlations, known as the proximity effect, but also modifies the density of states at some distance from the interface. These modifications can be resolved experimentally in microstructured systems. We therefore study the local density of states N(E ,x) of a superconductor–normal-metal heterostructure. We find a ...
