Quantum interference effects in [Co/Bi]n thin films
Magnetoconductivity (MC), Δσ(Β), and Hall coefficient, RH(B), measurements have been performed in polycrystalline thin films of Bi(15nm), Bi(10nm)/Co(1nm)/Bi(10nm) trilayer and [Co(0.7nm)/Bi(2nm)]10 multilayer, grown by magnetron scattering. The temperature dependence of RH(B) curves reveal the exi...

| Summary: | Magnetoconductivity (MC), Δσ(Β), and Hall coefficient, RH(B), measurements have been performed in polycrystalline thin films of Bi(15nm), Bi(10nm)/Co(1nm)/Bi(10nm) trilayer and [Co(0.7nm)/Bi(2nm)]10 multilayer, grown by magnetron scattering. The temperature dependence of RH(B) curves reveal the existence of a second conduction channel below 250K, that can be assigned to surface states. MC measurements between ±0.4T show at 5K an interplay between weak-antilocalization (WAL) in Bi and Bi/Co/Bi films and weal-localization (WL) in [Co/Bi]10 multilayer.
