  We study thermoelectric effects in Kondo correlated quantum dot coupled to
ferromagnetic electrodes by calculating conductance, thermopower and thermal
conductance in the Kondo regime. We also study the effect of the asymmetry in
the coupling to the leads, which has important consequences for anti-parallel
magnetization configuration. We discuss the thermoelectric figure of merit,
tunnel magnetoresistance and violation of the Wiedemann-Franz law in this
system. The results agree with recently measured thermopower of the quantum dot
defined in a two dimensional electron gas.
