摘要：
A role of interference and electronic correlations in a transport through molecular devices is considered within an extended Anderson model. In magnetic systems correlations reduce the value of the magnetoresistance, which can even change its sign in some cases. Transport studies through a two-atomic molecule showed a series of voltage ranges with characteristic current dependences. For strong Coulomb interactions the studies predict bistable current solutions.
