Heusler Alloy Thin Films for Spin Seebeck Devices

Abstract: The spin Seebeck effect 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 spin Seebeck based devices, where, in previous PNR we observed indications of inter-diffusion leading to a magnetic dead layer at the CMS/Pt that could have a dramatic effect on the functionality of any potential device. Here we propose to explore [Co2MnSi:Pt]2 multilayer stacks of this material characterising the Pt:CMS interface so that we can begin to explain stark differences in spin Seebeck enhancement for multilayer devices.
