Abstract
Transport through a quantum dot defined in a two-dimensional electron gas is investigated for a magnetic field parallel to the current direction. By measuring the differential conductance as a function of the gate-voltage for finite bias-voltage between the two electron reservoirs, excited states of the quantum dot are observable. Different excited states show a different magnetic field dependence. The observed shift of conductance resonances is affected by the diamagnetic shift of the two-dimensional electron gas in the leads.
