Abstract

Thermospintronics: spintronics just got hotter In 1821, Thomas Johann Seebeck found that electricity is generated from heat: the thermoelectric or Seebeck effect is used to generate electric power and also in the thermocouple, commonly used for temperature sensing. In the thermocouple two pieces of metal with different Seebeck coefficients, which determine the ratio of generated voltage to the temperature difference, are connected to each other. In theory there should be a 'spintronic' equivalent of the thermocouple — and now there is one in practice. Uchida et al. used a recently developed spin detection technique based on the spin Hall effect to demonstrate the spin-Seebeck effect for the first time, using it to obtain pure spin currents, a flow of spins without electric currents, over millimetre distances. The spin-Seebeck effect can generate the 'spin power' to drive spintronic devices, opening the way to the development of thermospintronics.
