Pure spin current vs. spin-polarized charge current?

  1. Apr 6, 2009 #1
    Is there anyone who understands (or has ever heard of) the difference between a pure spin current and a spin-polarized charge current?

    It causes a great deal of confusion for me, because I cannot imagine a current flowing without an accompanying charge flow... Guesses and conjectures are welcome. I have been struggling about this for quite some time now.

    Here's the paper and the context if you are interested in learning more:

    I don't want to believe that nobody has even an opinion on this!
