Abstract
Energy loss due to ohmic heating is a major bottleneck limiting down-scaling and speed of nanoelectronic devices. Harvesting ohmic heat for signal processing is a major challenge in modern electronics. Here we demonstrate that hermal gradients arising from ohmic heating can be utilized for driving auto-oscillations of magnetization in a ferrimagnetic nanowire via the spin Seebeck effect and for generation of tunable microwave signals. Our work paves the way towards spin caloritronic microwave and magnonic nanodevices.
