We investigate conductances and current correlations in a system consistingof a normal multichannel conductor connected to one superconducting and twoferromagnetic electrodes. For antiparallel orientation of the ferromagnetpolarizations, current injection from one ferromagnet can, due to Andreevreflection, lead to a net drag of current from the second ferromagnet towardthe superconductor. We present the conditions for the Andreev drag in terms ofthe degree of lead polarizations, contact conductances and spin-flipscattering. Remarkably, both equilibrium and nonequilibrium zero-frequencycurrent correlations between the ferromagnets become positive even in thepresence of spin relaxation.Comment: 5 pages, 3 figures; published version, added reference
