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.}, keywords = {J (WoSType)}, cin = {PGI-2}, ddc = {550}, cid = {I:(DE-Juel1)PGI-2-20110106}, pnm = {Grundlagen für zukünftige Informationstechnologien}, pid = {G:(DE-Juel1)FUEK412}, shelfmark = {Physics, Multidisciplinary}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000293921000023}, doi = {10.1103/PhysRevLett.107.087202}, url = {https://juser.fz-juelich.de/record/19916}, }
