Abstract
It is shown theoretically that the conversion of spin-up into spin-down current near a ferromagnetic-nonferromagnetic metal interface gives rise to an electrochemical potential difference of spin-up and spin-down electrons. The effect shows up as an additional boundary resistance. The situation is analogous to the normal-metal-superconductor interface. Experimental methods that may be used to observe the effects are discussed.Keywords
