Abstract

We self-consistently investigate electron transport through a quantum dot with competitions between the electron-electron correlation interaction and the spin interaction from dilute ferromagnetic impurities and conduction electrons at low temperatures. The numerical results show that the defects, caused by the impurities in the antiferromagnetic state around half filling, lift up the bottom of the conductance valley which is caused by the electron-electron correlation interaction.
