Theoretical analysis of resonant electronic transport through a non-interacting single level quantum dot attached to ferromagnetic leads has been carried out. An external magnetic field is applied to the system, which leads to spin splitting of the dot level. Magnetic moments of the leads and the external magnetic field are assumed to be noncollinear.

However, all of them are in a common plane. Transport characteristics are calculated using the nonequlibrium Green function technique, and the Green functions have been calculated via the equation of motion method. Dependence of the transport characteristics on the system parameters are discussed from the fundamental and application points of view.
