500 _ _ |a We acknowledge stimulating discussions with B. Sothmann, J. Konig, and S. Andergassen. and the financial support from NanoSci-ERA and DFG (FOR 912).
520 _ _ |a We show that spin anisotropy can be transferred to an isotropic system by transport of a spin-quadrupole moment. We derive the quadrupole moment current and continuity equation and study a spin-valve structure consisting of two ferromagnets coupled to a quantum dot probing an impurity spin. The quadrupole backaction on their coupled spin results in spin torques and anisotropic spin relaxation which do not follow from standard spin-current considerations. We demonstrate the detection of the impurity spin by charge transport and its manipulation by electric fields.
