Kondo Effect in the Presence of Magnetic Impurities
Kondo Effect in the Presence of Magnetic Impurities
We measure transport through gold grain quantum dots fabricated using electromigration, with magnetic impurities in the leads. A Kondo interaction is observed between dot and leads, but the presence of magnetic impurities results in a gate-dependent zero-bias conductance peak that is split due to a RKKY interaction between the spin …
