We report unconventional thermoelectric power (Seebeck coefficient, S) in L10structured FePt films. The temperature dependence of S can be well fitted by aphenomenological expression consisting of electron diffusion and magnon-dragcontributions. Interestingly, the magnon drag coefficient carries an oppositesign to that of electron diffusion, revealing a dominant contribution from theelusive electron-magnon Umklapp scattering. DFT calculations identify severalbands crossing the Brillouin zone boundaries, facilitating the Umklapp process.The large spin-orbit coupling in FePt results in strong mixing of majority andminority spins among some of those bands, greatly enhancing the electron-magnonscattering.
