We propose a two-terminal spin-orbit interferometer with a hot molecule inserted in one of its arms to generate pure spin currents. Local heating is achieved by coupling the vibrational modes of the molecule to a third (phononic) reservoir. We show that this spin calorimetric effect is due to the combined influence of spin-dependent wave interference and inelastic scattering. Remarkably, the device converts heat flow into spin-polarized current even without applying any voltage or temperature…

Application of small static magnetic fields results in a Hanle effect which permits determination of the spin-relaxation time, and the unique features of the method should make it applicable to a wide range of studies.

Observation of the spin Seebeck effect
The spin Seebeck effect allows us to pass a pure spin current, a flow of electron spins without electric currents, over a long distance, and is directly applicable to the production of spin-voltage generators, which are crucial for driving spintronic devices.
