  • Magnetoresistance in Co/AlOx/Co tunnel junction arrays
  • 2002

  • Journal article (peer-reviewed)abstract
    • Lateral arrays of Co/AlOx/Co junctions with dimensions down to 60 nin and inter-junction separations similar to60-100 nm have been fabricated and analyzed for possible coherent tunneling effects. Extra attention is paid to avoid uncertainties due to inconsistencies in switching and/or resistance of successive barriers. We observe similar to10% magnetoresistance enhancement at moderate bias in double junctions that cannot be accounted for by a simple model of two resistsors in series.

  • Spin injection in ferromagnet-superconductor/ normal-ferromagnet structures
  • 2004
  • In: Journal of Magnetism and Magnetic Materials. - : Elsevier BV. - 0304-8853 .- 1873-4766. ; 272-276/ Suppl, s. 1469-1470
  • Journal article (peer-reviewed)abstract
    • We have fabricated multi-terminal devices consisting of three parallel ferromagnetic ( FM) electrodes with tunnel junction contacts to a 100 nm wide Al strip. A spin polarized current injected from one FM electrode into the Al strip can be detected at the other FM electrodes. The spin diffusion length and polarization in Al are measured at room temperature (RT), and at 4 K: No magnetoresistance (MR) over two junctions in series could be measured with the strip in the normal state. A weak MR is observed in the superconducting (S) state.
