## Long-range supercurrents through half-metallic ferromagnetic CrO2

Description : We report on measurements of supercurrents through the half-metallic ferromagnet CrO2 grown on hexagonal Al2O3 (sapphire). The current was observed to flow over a distance of 700 nm between two superconducting amorphous Mo70Ge30 electrodes which were deposited on the CrO2 film. The critical current ...

## Magnetization-induced resistance-switching effects in La0.67Sr0.33MnO3/YBa2Cu3O7â��Î´ bi- and trilayers

Description : We have studied the influence of the magnetization on the superconducting transition temperature (Tc) in bi- and trilayers consisting of the half-metallic ferromagnet La0.67Sr0.33MnO3 and the high-temperature superconductor YBa2Cu3O7â��Î´ (YBCO). We have made use of tilted epitaxial growth in order ...

## Depairing currents in the superconductor/ferromagnet proximity system Nb/Fe

Description : We have investigated the behaviour of the depairing current J_{dp} in ferromagnet/superconductor/ferromagnet (F/S/F) trilayers as function of the thickness d_s of the superconducting layers. Theoretically, J_{dp} depends on the superconducting order parameter or the pair density function, which is...

## Strain release of (La,Ca)MnO3 thin films by YBa2Cu3O7-d

Description : La1-xCaxMnO3 (x = 0.3; LCMO) films of different thickness were sputter-deposited on SrTiO3(100) (STO) single crystal substrates with and without YBa2Cu3O7-d (YBCO) as template layer. The electric and magnetic properties and the microstructure of the films were studied. Clear differences in the out...

## Disorder-induced melting of the charge order in thin films of Pr0.5Ca0.5MnO3

Description : We have studied the magnetic-field-induced melting of the charge order in thin films of Pr0.5Ca0.5MnO3 (PCMO) films on SrTiO3 (STO) by X-ray diffraction, magnetization and transport measurement. At small thickness (25 nm) the films are under tensile strain and the low-temperature melting fields ar...

## STM Imaging of Flux Line Arrangements in the Peak Effect Regime

Description : We present the results of a study of vortex arrangements in the peak-effect regime of 2H-NbSe_2 by scanning tunneling microscopy. By slowly increasing the temperature in a constant magnetic field, we observed a sharp transition from collective vortex motion to positional fluctuations of individual...

## Critical voltage of a mesoscopic superconductor

Description : We study the role of the quasiparticle distribution function f on the properties of a superconducting nanowire. We employ a numerical calculation based upon the Usadel equation. Going beyond linear response, we find a non-thermal distribution for f caused by an applied bias voltage. We demonstrate...

## Vortex relaxation and coupling in superconducting heterostructures studied by STM

Description : In a sandwich consisting of two superconducting films, one weakly pinning and one strongly pinning, the vortex positions in both films are determined by the strongly pinning material and the vortex lattice is disordered in both films. We used (strongly pinning) NbN and (weakly pinning) MoGe and st...

## In search for the superconducting spin-switch: Magnetization induced resistance switching effects in La$_{0.67}$Sr$_{0.33}$MnO$_3$/YBa$_2$Cu$_3$O$_{7-\delta}$ bi- and trilayers

Description : We have studied the influence of the magnetization on the superconducting transition temperature ($T_c$) in bi- and trilayers consisting of the half-metallic ferromagnet La$_{0.67}$Sr$_{0.33}$MnO$_3$ (LSMO) and the high-temperature superconductor YBa$_2$Cu$_3$O$_{7-\delta}$ (YBCO). We have made us...
