| Abstract: | The efficiency of injection of charge carriers with a definite spin into a ferromagnetic material in the ferromagnet/nonmagnetic
metal/ferromagnet three-layer structure is analyzed taking into account the contribution from the nonmagnetic layer. It is
shown that in the Co/Cu/Fe structure, the efficiency of spin injection is several times higher than in the Co/Cu/Co symmetric
structure. Optimal conditions of injection of charge carriers with a definite spin depending on the parameters of used material
are established. |
