We report Co59 NMR measurements on three MBE-grown Co/Cu(111) multilayer films that show a progression of saturation magnetoresistance from ΔR/R=4% to ΔR/R=40%. Our results demonstrate unambiguously that the increase in magnetoresistance is correlated with an improvement in the quality of the interfaces in these MBE-grown materials. © 1994 The American Physical Society.
