  We present first room-temperature thermoelectric signature of the skyrmion
lattice. This was observed in Fe3Sn2, a Kagome Dirac crystal with massive Dirac
fermions that features high-temperature skyrmion phase. The room-temperature
skyrmion lattice shows magnetic-field dependence of the wavevector whereas
thermopower is dominated by the electronic diffusion mechanism, allowing for
the skyrmionic bubble lattice detection. Our results pave the way for the
future skyrmion-based devices based on the manipulation of the thermal
gradient.
