| Outline of Final Research Achievements |
We introduced the term “spin mechanics” to describe the physics of the magnetic order interacting with the mechanical degrees of freedom in nanoscale materials and devices, comprising the Barnett and Einstein de Haas effects, magnetoelasticity, and magnon-phonon interactions. We reported our progress in spin mechanics, spintronics, and spin caloritronics in many publications as well as invited conference talks. We pragmatically developed theoretical models that lead to testable results, from atomistic simulations of complex ferrimagnets, to ballistic and semiclassical calculations of the response to perturbations such as temperature gradients and optical pulses, and effective diffusion equations of magnon transport. Highlights are our contributions to the discoveries of the spin Hall magnetoresistance, magnon polarons in optical pump-probe and spin Seebeck transport experiments, spin Peltier and spin Nernst effects, and the prediction of phonon pumping by magnetization dynamics.
