We consider a two-atom molecule connected to ferromagnetic leads, in the Kondo transport regime. To investigate the Kondo effect in the system, we use the slave-boson mean field approximation (SBMFA) techniques. Results are obtained for both the strong interaction limit, in which an infinite Coulomb repulsion U1-2 between atoms is assumed, and a finite U1-2 case. The transport is considered in the T = 0 and V = 0 equilibrium limit.
