Tunneling electrons through a magnetic dielectric

  1. Apr 23, 2007 #1

    I am trying to learn something about how experimental physics is done.
    I am very new at it and am looking for experienced guidance.

    A friend of mine (zapperz) suggested that a good way to measure the effect of a
    magnetic field on electrons in the tunneling state is to have the
    electrons tunnel through a dielectric with a magnetic moment.

    I have seen papers on this but they refer to superconductivity. I
    don't think I need to add that to the mix.

    Actually, if you read the paper that I referred to carefully, while the metallic electrodes are superconductors (actually, only one is while the other is a normal metal), what you should have been focusing on is the oxide layer that is in between these electrodes. This IS the tunneling barrier that contains the magnetic moment. So you could have two normal metals here with the same barrier.

    Oh - that's perfect. I will read it more carefully.
