The electromagnetically induced left-handedness in a four-level atomic system associated with a pair of upper excited hyperfine levels has been investigated. The properties of left-handedness with vacuum-induced coherence (VIC) arising from the cross coupling spontaneous emission pathways have also been discussed. The theoretical analyses show that the left-handedness of medium will be enhanced with the increase of VIC effect.
