We consider nonequilibrium electron transport through a quantum dot in the Kondo regime coupled by exchange interactions to a second quantum dot connected to a third reservoir. The current is evaluated in perturbation theory. In a magnetic field it is shown to depend on the nonequilibrium magnetization in an essential way. The dependence of the magnetizations of both quantum dots on the exchange coupling, the magnetic field and temperature is calculated. description: Nonequilibrium transport through Quantum Dot Systems in the Kondo Regime
