Manipulation of Coupling and Magnon Transport in Magnetic Metal-Insulator Hybrid Structures
Manipulation of Coupling and Magnon Transport in Magnetic Metal-Insulator Hybrid Structures
Ferromagnetic metals and insulators are widely used for generation, control and detection of magnon spin signals. Most magnonic structures are based primarily on either magnetic insulators or ferromagnetic metals, while heterostructures integrating both of them are less explored. Here, by introducing a Pt/yttrium iron garnet (YIG)/permalloy (Py) hybrid structure grown …
