Abstract

As spintronic devices continue to shrink toward nanoscale dimensions, interest has grown in the role that heat plays in these systems. Thermal gradients in spintronics can be unintentional, such as those generated by the high current densities often required to switch nanoscale magnets, or intentional, such as when studying materials using thermal probes. Here we focus on how the heat and charge flow in a ferromagnetic metal can be altered when long-lived spin dynamics are present. Using unique micromachined thermal isolation platforms, we demonstrate a unique magnetic-field direction dependence in thermal properties of alloys with exceptionally low magnetic damping.
