摘要
Superconductor-ferromagnetic in-planenanocontacts have been created with focused-electron/ion-beam-induced deposition techniques for studies of AndreevReflection. The final resistance of the nanocontact is tuned during the growth by in situ resistance measurements. The results show that Co nanodeposits grown with focused electron beam have large spin polarizatiomn (-35%), making this nanomaterial of great potential for use in Spin Electronics applications. The experiments have also allowed the determination of the superconducting gap of the W-based nanodeposits grown with focused ion beam.
