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...
