Electric field effect on superconductivity in La2−xSrxCuO4

Electric field effect on superconductivity in La22xSrxCuO4

We demonstrate a method to tune the carrier concentration of a high temperature superconductor over a wide range, using an applied electric field. Thin film devices were made in an electrical double layer transistor configuration utilizing an ionic liquid. In this way, the surface carrier density in La2ÿxSrxCuO4 films can be varied between 0.01 and 0.14 carriers per Cu atom with a resulting cha...

Electric field effect on cholesterol-phospholipid complexes.

Monolayer mixtures of dihydrocholesterol and phospholipids at the air-water interface are used to model membranes containing cholesterol and phospholipids. Specific, stoichiometric interactions between cholesterol and some but not all phospholipids have been proposed to lead to the formation of condensed complexes. It is reported here that an externally applied electric field of the appropriate...

Magnetic field effect on the pseudogap temperature within precursor superconductivity.

We determine the magnetic-field dependence of the pseudogap closing temperature T* within a precursor superconductivity scenario. Detailed calculations with an anisotropic lattice model with d-wave superconductivity account for a recently determined experimental relation in BSCCO between the pseudogap closing field and the pseudogap temperature at zero field, as well as for the weak initial dep...

Effect Of Electric Field On Liquid Viscosity in Co-Axial Cylindric Pipes

Electric field effect on magnetism in metallic ultra-thin films

Recent experimental developments on the electric field effect on magnetism in metallic magnetic materials are reviewed. The change in the electron density at the surface of metallic ultra-thin magnets by the application of an electric field results in modulations of the Curie temperature, magnetic moment, magnetic anisotropy, and domain wall velocity. The study focused on this paper is the elec...
