Since the discovery of giant magnetoresistance, spintronics research has been evolving and has reached a new phase in which the concept of spin currents, i.e., the flow of spin angular momenta, helps us understand various spintronics phenomena. These include all the recently discovered conversion phenomena, such as the direct and inverse spin Hall effects, spin Seebeck and Peltier effects, spin pumping, and the inverse Faraday effect. More recently, Rashba interfaces and the surface states of topological insulators were found to exhibit the so-called Edelstein effect, in which spin-momentum locking behavior brings about non-equilibrium spin accumulation. These interface and surface effects thus provide an effective means of interconversion among spin, charge, and heat currents. Most of the above-mentioned spin conversion phenomena take place at simple nanoscale interfaces between two different types of materials (e.g., magnets, non-magnets, semiconductors, and insulators). These structures may enable us to advance spin-mediated interconversion among physical entities such as electricity, light, sound, vibration, and heat
The symposium on Spin Conversion Phenomena in Spin-Orbit Materials deals with all the interconversion phenomena among electrons, phonons, magnons, and photons mediated by spins.
The aim of the workshop is to provide an international/global forum for discussions of interdisciplinary issues on “spin torque induced dynamics of spin structures such as domain walls and skyrmions”, “spin to charge conversion phenomena due to spin Hall effects in topological materials and spin momentum locking at the surface and interface states”, “optically induced collective and also coherent quantum spin dynamics” and “thermally and mechanically created spin currents”.
