Abstract
We present a simple Ohmic model to calculate the current distribution in small pillar-like structures for perpendicular magnetoresistance experiments. These calculations are consistent with three-dimensional electrostatic simulations, based on the finite element method, and facilitate the analysis of magnetoresistance data of microstructured multilayers.This publication has 15 references indexed in Scilit:
