Ultrafast Charge, Spin, and Lattice Coupling Facilitates Spin Transport as Magnon–Polarons in Yttrium Iron Garnet

ABSTRACT Low spin damping and long spin‐polarization lifetimes are essential for spintronic and spin‐based energy‐conversion technologies, yet their microscopic origin in magnetic insulators remains poorly understood. Yttrium iron garnet (YIG), a prototypical magnetic insulator e...
