Heusler Alloy Thin Films for Spin Seebeck Devices

Abstract: The spin Seebeck effect (SSE) is a relatively new phenomenon that could be harnessed for waste heat recovery. Its advantages lie with a new device architecture (compared to conventional thermoelectric generators) that would not only reduce the cost of fabrication but also enable separation of the key drivers of device efficiency: electric and thermal conductivity of certain active components. We are exploring Co2MnSi as a potential material for SSE based devices, where in previous PNR we observed indications of a magnetic dead layer (within the bulk of the film) that could have a dramatic effect on the functionality of any potential device. We propose to explore this feature further whilst also characterising basic device components. This will enable determination of isotropically structured spin generating material, in the hope of creating a 100% spin polarised half metal.
