  We find an unusual angular dependence of the tunneling magneto-Seebeck effect
(TMS). The conductance shows normally a cosine-dependence with the angle
between the magnetizations of the two ferromagnetic leads. In contrast, the
angular dependence of the TMS depends strongly on the tunneling magneto
resistance (TMR) ratio. For small TMR ratios we obtain also a cosine-dependence
whereas for very large TMR ratios the angular dependence approaches a step-like
function.
