The spin Seebeck effect (SSE) is a newly discovered phenomenon that if harnessed, could result in a significant improvement of the efficiency of thermoelectric generators. The SSE is the generation of a spin polarised current when a magnetic material is subjected to a temperature gradient and is typically measured indirectly using the inverse spin Hall effect. Polarised neutron reflectivity can provide complementary data that enable determination of the spin polarisation of the film and the magnetic ordering at the surface and interface. This is especially important as the influence of the interface is still not well understood.We propose using PNR in conjunction with an adapted sample environment to investigate the magnetic depth profile of a multi-layer sample for different temperature gradients. The fundamental aim is to demonstrate direct observation of the SSE for the first time.
