Abstract
Combining the transfer matrix method with Landauer-Büticker formalism, we study the spin-polarized transport in the current-perpendicular-to-the plane (CPP) geometry of a quasiperiodic magnetic multilayered structure consisting of a ferromagnet (FM) and a nonmagnet (NM) arranged in a Fibonacci sequence. The CPP giant magnetoresistance (GMR) in the quasiperiodic structure is found to be largely enhanced compared with that in the periodic one. It is also shown that there are the same and different properties in the variations of the relative conductivities and of the GMR with the number of bilayers between the quasiperiodic and periodic structures, implying that there exist common and different physical origins in them.
