Abstract

The present study is motivated by two considerations: to theoretically obtain a solution of magnetoresistance other than a simple layered structure, and to optimize the magnitude of the resistance and magnetoresistance through a geometrically controlled parameter. We have evaluated the resistance and magnetoresistance as a function of the size of a geometrically confined constriction by explicitly solving the macroscopic spindiffusion equations. If we use sets of transport parameters previously found in magnetic multilayered structures, we are able to make a quantitative prediction on the resistance and magnetoresistance in the confined structure.
