Abstract EN

In this work, the transport properties for a quantum dot under the effect of external magnetic field, embedded between two ferromagnetic leads is studied in the case where the correlation energy goes to infinity.

We use the theory of Keldysh non-equilibrium Green's functions technique to formulate mathematical model to calculate the occupation numbers of the quantum dot, the current in addition to the charge conductance and spin conductance as a function of the spin bias in the leads .

we conclude that the transport properties are determined by the magnetic field effect as well as the bias in spin.
