The use of a numerical renormalization group (NRG) to study the Kondo effect in a quantum dot was discussed. The Kondo effect was found to be robust against polarizations in case of symmetric Anderson model, where charge fluctuations are completely suppressed. For the asymmetric Anderson model, the Kondo peak was found to split into two parts. The linear tunneling magnetoresistance (TMR) and the influence of spin-flip processes were also discussed.
