Abstract
We applied giant magnetoresistance (GMR) effect to measure spin diffusion l ength in a non-magnetic metal. The temperature dependence of the magnetores istance observed in Fe/Cu/Ni tri-layer samples was strongly dependent on th e thickness of the middle Cu layers, apparently reflecting the spin diffusi on length. Assuming the error-function dependence on the thickness, we deri ved the values of the spin diffusion length. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
