Spintronics, Magnonics, and Magneto-Optical Materials
This community investigates the fundamental physics of spin and orbital angular momentum in magnetic materials, with a focus on manipulating these properties for information processing, sensing, and quantum technologies.
The research centers on rare-earth iron garnets, particularly yttrium iron garnet (YIG), and their thin-film counterparts. Key topics include magneto-optical Kerr effect measurements, spin-orbit torque switching, spin Hall effects, and the generation and control of spin waves (magnons). The work also covers topological insulators, chiral magnets, and magnetic tunnel junctions. Recent attention is directed toward orbital torque mechanisms, quantum magnon squeezing, and the integration of these materials into memory devices like spin-orbit torque magnetic random-access memory (SOT-MRAM).
The community is most prominent in yttrium research, representing 8.5% of all tracked yttrium literature, and in iron research, accounting for 4.9% of that element's output. It also holds a 5.2% share of terbium research.
The group comprises 9,360 papers, primarily published in the Journal of Applied Physics, Physical Review B, and Applied Physics Letters.
Recent work includes studies on orbital current torque in bilayers, doped yttrium iron garnet ceramics for microwave performance, quantum magnon squeezing, and the development of back-end-of-line-compatible SOT-MRAM devices.
