In the limit that the phase-breaking and spin flip scattering lengths are greater than the system size, a multiple-scattering approach is used to calculate the 4-probe conductance. We show that by tuning the strength of tunnel barriers placed between the current and voltage probes giant magnetoresistance ratios of arbitrary strength and size are achievable.4 page, 4 figuresMesoscale and Nanoscale PhysicsStrongly Correlated Electronstext
