Observation of the Nernst effect driven by longitudinal spin fluctuations
Fuyuki Ando, Hiroto Adachi, Hossein Sepehri-Amin +3
The Nernst effect, which converts a heat current into a charge current in the orthogonal direction, is generally classified into the ordinary effect due to an external magnetic fie…
Semiclassical thermoelectric transport in disordered Dirac electron system Ag2Te
Kentaro Kuga, Keisuke Hirata, Daiki Goto +3
We investigated the thermoelectric effects of the Dirac electron system Ag2Te under magnetic field. Our anal-ysis based on the Boltzmann semiclassical model associated the disorder…
