Query: Tunneling magneto thermocurrent in CoFeB/MgO/CoFeB based magnetic tunnel
  junctions   We study the tunneling magneto thermopower and tunneling magneto
thermocurrent of CoFeB/MgO/CoFeB magnetic tunnel junctions (MTJ). The devices
show a clear change of the thermoelectric properties upon reversal of the
magnetisation of the CoFeB layers from parallel to the antiparallel
orientation. When switching from parallel to antiparallel the thermopower
increases by up to 55% where as the thermocurrent drops by 45%. These
observations can be well explained by the Onsager relations taking into account
the tunneling magneto resistance of the MTJ. These findings contrast previous
studies on AlO based MTJ systems, revealing tunneling magneto thermo power but
no tunneling magneto thermocurrent.
