The Meservey-Tedrov effect in FSF double tunneling junctions
Gerd Bergmann, Jia Lu, Dawei Wang
Double tunneling junctions of ferromagnet-superconductor-ferromagnet electrodes (FSF) show a jump in the conductance when a parallel magnetic field reverses the magnetization of on…
Localization and superconducting proximity effect in sandwiched potassium films
Manjiang Zhang, Gerd Bergmann
Thin films of alkali metals when sandwiched at both surfaces by thin metal films loose their conductance. The superconducting proximity effect is used to investigate the change in…
The Superconducting Proximity Effect as a Tool to Investigate Metal Films and Interfaces
D. Garrett, M. Zhang, G. Bergmann
052<p type="texpara" tag="Body Text" et="abstract" >The superconducting proximity effect is measured in sandwiches of thin Pb films and the alkali metals Cs, Rb, K and Na. The $T_{…
Induced Spin-Currents in Alkali-Films
Gerd Bergmann, Funing Song, Doug Garrett
In sandwiches of FeK and FeCs the conduction electrons in the alkali metals have a large mean free path. The experiments suggest that the specular reflection for spin up and down e…
