1. The interplay of spin, charge and heat at the nanoscale, governed by the spin-orbit interaction, thermoelectrics and spin caloritronics, is ex-pected to be a crucial component for next-generation logic and memory devices.
2. Thermoelectric effects can mimic spin-related phenomena in spin trans-port experiments and therefore, need to be carefully analyzed and cor-rectly interpreted. [Chapter 4]
3. Working on challenging device architectures often requires multiple it-erations, with continuous design and process improvements, before it can be finally mastered. [Chapter 5]
4. Spin-orbit interaction, together with the magnetization order parameter in ferromagnetic materials, can be utilized to realize efficient and tun-able injection, detection and manipulation of spin currents. [Chapters 7-9]
5. Collaborative research enables the flow of ideas between different disci-plines and the availability of multiple resources directed towards solv-ing complex scientific problems. Therefore, it should be encouraged. 6. The transferable skills developed during a PhD are often
underesti-mated or ignored. PhD students should be aware of these skills and take every opportunity during their PhD to develop them even further. 7. Non-violence and compassion begin on your plate.
8. Meditation, yoga and leading a healthy lifestyle enable you to be more productive and handle stress better.
