Generation, Detection, and Control of Coherent Magnon Transport and Condensation in a Two-Dimensional Magnet
Abstract
Due to their high crystalline quality and ease of device integrability, two-dimensional (2D) magnetic materials offer a fertile playground for both the investigation of novel spin physics and development of high-performance spintronic devices that is unavailable to traditional magnetic compounds. Despite the tremendous advances in these areas in the past few years, there have been few reports using such materials to realize spin wave or magnonic devices. As magnons are coherent information carriers, they can be exploited for novel classical and quantum information technologies, such as neuromorphic computing, quantum transduction, and ensemble qubits. Currently, most magnonic systems incorporate the three-dimensional magnetic insulator yittrium iron garnet, which has limited tunability and is further difficult to grow as high-quality thin films. For this project, we shall develop a unified platform for the study of coherent magnon transport and condensation using 2D magnets and heterostructures. We shall specifically target the CrXBr (X = S, Se) family of magnetic semiconductors and build several device geometries to excite, detect, and control for both independent magnons and a magnon Bose-Einstein condensate (BEC). In particular, the following two main objectives will be carried out over a three-year period.
