We present an exact analytical method to calculate the electronic transmission coefficient of ferromagnetic nanowires based on Green's function theory and tight-binding approach. To this end, we obtain the spin-dependent self-energies of the nanowire due to the existence of ferromagnetic leads and derive the elements of system Green's function matrix. Spin-dependent electron transport via some configurations of a ferromagnetic nanowire including magnetic defects is investigated in detail. Further, we analyze the electron reflection from an ideal semi-infinite magnetic chain with different moments at the edge. The results can be useful to simulate and develop magnetic and spintronic nano-devices.
