  A new measurement technique for the spin Seebeck effect is presented, wherein
the normal metal layer used for its detection is exploited simultaneously as a
resistive heater and thermometer. We show how the various contributions to the
measured total signal can be disentangled, allowing to extract the voltage
signal solely caused by the spin Seebeck effect. To this end we performed
measurements as a function of the external magnetic field strength and its
orientation. We find that the effect scales linearly with the induced rise in
temperature, as expected for the spin Seebeck effect.
