Unconventional charge order in a co-doped high-Tc superconductor
Charge-stripe order has recently been established as an important aspect of cuprate high-Tc superconductors. However, owing to the complex interplay between competing phases and the influence of disorder, it is unclear how it emerges from the parent high-temperature state. Here we report on the discovery of an unconventional ordered phase between charge-stripe order and (pseudogapped) metal in ...
متن کاملInhomogeneous magnetism induced in a superconductor at superconductor-ferromagnet interface
We study a magnetic proximity effect at superconductor (S) ferromagnet (F ) interface. It is shown that due to an exchange of electrons between the F and S metals ferromagnetic correlations extend into the superconductor, being dependent on interface parameters. We show that ferromagnetic exchange field pair breaking effect leads to a formation of subgap bands in the S layer local density of st...
متن کاملCharge Distribution in C60 Crystal Doped by Electric Field
The calculations of the charge distribution in the C60-based FET structure are presented. A simple model is proposed to describe the distribution of injected electrons or holes between two-dimensional layers. The calculations show that the relative layer charges are independent on the total amount of injected charges. The charge density is maximal on the surface layer and drops exponentially wi...
متن کاملThe intermodulation coefficient of an inhomogeneous superconductor
The high-Tc cuprate superconductors are now believed to be intrinsically inhomogeneous. We develop a theory to describe how this inhomogeneity affects the intermodulation coefficient of such a material. We show that the continuum equations describing intermodulation in a superconducting layer with spatially varying properties are formally equivalent to those describing an inhomogeneous dielectr...
متن کاملAnomalous Fermi-surface dependent pairing in a self-doped high-Tc superconductor.
We report the discovery of a self-doped multilayer high Tc superconductor Ba2Ca3Cu4O8F2 (F0234) which contains distinctly different superconducting gap magnitudes along its two Fermi-surface sheets. While formal valence counting would imply this material to be an undoped insulator, it is a self-doped superconductor with a Tc of 60 K, possessing simultaneously both electron- and hole-doped Fermi...
