In this paper, transmission resonance and conductance properties of nonequilibrium quantum dot connected by ferromagnetic leads are investigated. Thermoelectric properties are also studied. Using the tight-binding formalism and numerically solving the Schrodinger equation, spin-dependent transmissions are obtained and plotted as a function of incoming electron energy. Transmissions of spin up and spin down electrons change in different ways as voltage bias and tilt angle change. Current spin polarization can be sensitively tuned by adjusting voltage bias. These research indicates the possible methods to modulate tilt angle or the bias voltage to obtain spin-dependent transmission, spin polarized current and effective Seebeck coefficients.
