β¦ Synopsis
Electronic and magnetic structures in magnetic multilayers and granular alloys are examined. It is shown that the structures govern the giant magnetoresistance. We present a simulation method of the resistance and magnetoresistance based on the recursive Green's function method. By using this method, the dependencies of the magnetoresistance on materials and nanostructure of the systems are derived.

We have measured magnetoresistance (MR) for semimetals Bi and graphite, nearly gapless materials Bi-Sb and Bi-Te alloys, and narrow gap semiconductor Ag 2 Se single crystals at 4.2 K and up to 4 T. We have observed a giant MR for Bi, a giant linear MR (LMR) for Bi-Sb alloy and Ag 2 Se single crystal
## Abstract The effects of inhomogeneous compression of gas diffusion layers (GDLs) on local transport phenomena within a polymer electrolyte membrane (PEM) fuel cell were studied theoretically. The inhomogeneous compression induced by the rib/channel structure of the flow field plate causes partia
