Abstract: We investigate the thermoelectric properties of electrons at the interface of an oxide heterostructure and in the presence of a multiferroic oxide with spiral spin order. We find that there is no (spin) Hall current generated by the temperature gradient. A Seebeck effect is, however, present. Due to the magnetoelectric coupling, the charge and thermal conductivities are electrically controllable via the spin spiral helicity. Moreover, the thermopower exhibits a sign change when tuning the carrier density electro-statically.
