Andreev experiments on superconductor/ferromagnet point contacts
S. Bouvron, M. Stokmaier, M. Marz +1
Andreev reflection is a smart tool to investigate the spin polarisation P of the current through point contacts between a superconductor and a ferromagnet. We compare different mod…

Experimental verification of contact-size estimates in point-contact spectroscopy on superconductor/ferromagnet heterocontacts
J. Gramich, P. Brenner, C. Sürgers +2
Nanostructured superconductor/ferromagnet heterocontacts are studied in the different transport regimes of point-contact spectroscopy. Direct measurements of the nanocontact size b…

Size Dependence of Current Spin Polarization Through Superconductor/Ferromagnet Nanocontacts
M. Stokmaier, G. Goll, D. Weissenberger +2
The spin polarization P of the transport current through the interface between superconducting Al and ferromagnetic Fe is determined by means of Andreev reflection at nanostructure…
