      abstract     = {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.},
