An experimental/theoretical PhD in the area of “spin Seebeck effect and its application to energy harvesting” is currently being advertised, to start from June 2019.
Full Project Detail:
The spin Seebeck effect is a newly discovered phenomenon that manifests as the generation of a spin current when a magnetic material is subjected to a temperature gradient. For this reason, it is often classed with a larger group of effects under the umbrella term “spin caloritronics”, i.e. the interplay of spin and thermal currents. These effects have exciting potential for future electronic devices, in particular in the creation of efficient spin-based devices to harvest wasted energy from heat sources such as engines, boilers and computers.
The objective of this PhD is to develop new theoretical models to investigate the interplay between thermal and spin transport in spin Seebeck devices. The student will combine atomistic calculations of the material properties with Boltzmann transport calculations of coupled magnon-phonon transport to obtain a deep understanding of the fundamental physics of the spin Seebeck effect. These models will be used to design new structures for the next generation of spin caloritronic devices. The student will work closely with researchers carrying out experiments on these devices which will inform both the modelling and understanding of the experimental results. The student may also have the opportunity to carry out new experiments on this type of device and explore their own experimental proposals.
