Proposal for quantum spin tomography in ferromagnet-normal conductors

Samuelsson, Peter LU and Brataas, Arne (2010) In Physical Review B (Condensed Matter and Materials Physics) 81(18).
Abstract
We present a theory for a complete reconstruction of nonlocal spin correlations in ferromagnet-normal conductors. This quantum spin tomography is based on cross-correlation measurements of electric currents into ferromagnetic terminals with controllable magnetization directions. For normal injectors, nonlocal spin correlations are universal and strong. The correlations are suppressed by spin-flip scattering and, for ferromagnetic injectors, by increasing injector polarization.
