  We study a new hybrid normal-superconductor (NS) pi-junction in which the
non-local current can be orders of magnitude larger than that in earlier
proposed systems. We calculate the electronic transport of this NS hybrid when
an external magnetic field is applied. It is shown that the non-local current
exhibits oscillations as a function of the magnetic field, making the effect
tunable with the field. The underlying classical dynamics is qualitatively
discussed.
