Symposium EM8—Spin Dynamics in Nonmagnetic Materials and Devices

This symposium will represent fundamental advances and device implications of spin dynamics in materials and devices where the spin dynamics is occurring in a region which is not itself in a magnetic phase. The materials can be characterized by electronic band transport, hopping transport, or can be fully insulating, and the spin dynamics can occur due to exchange interactions, dipolar interactions, spin-orbit interactions or other effective torques present in nonmagnetic phases. They include spin-based color centers in diamond, silicon carbide, strontium titanate, and Dirac materials; room-temperature coherent spin systems based on diamond and silicon carbide are already beginning to make inroads into sensitive room-temperature magnetometry and entanglement-based secure communication. Persistent magnetization has been observed in oxides and topological insulators, both electrically and optically induced. Other examples are spin correlations in electronic transport and recombination, such as between singlet and triplet excitons, which play a major role in organic transport, organic light emitting diodes, and complex oxide tunnel junctions. Similar effects occur in the area of spin chemistry, which provides another avenue for biological effects of room-temperature spin coherence. Submissions are encouraged that report spin dynamics in new materials, that characterize its persistence and transport, the utilize it in new devices or report advances in the performance of current devices. The broad range of materials and devices in which room-temperature coherent spin dynamics already has been demonstrated suggests that this is a material property that can be found in a wide variety of new settings and devices. In order to focus on the directions of most immediate interest the emphasis of the symposium will be on materials and devices in which these effects occur at room temperature, or where a pathway towards room temperature is feasible.
