Magnon confinement in an all-on-chip YIG cavity resonator using hybrid YIG/Py magnon barriers

Abstract
Confining magnons in cavities can introduce new functionalities to magnonic devices, enabling future magnonic structures to emulate established photonic and electronic components. As a proof-of-concept, we report magnon confinement in a lithographically defined all-on-chip YIG cavity created between two YIG/Permalloy bilayers. We take advantage of the modified magnetic properties of covered/uncovered YIG film to define on-chip distinct regions with boundaries capable of confining magnons. We confirm this by measuring multiple spin pumping voltage peaks in a 400 nm wide platinum strip placed along the center of the cavity. These peaks coincide with multiple spin-wave resonance modes calculated for a YIG slab with the corresponding geometry. The fabrication of micrometer-sized YIG cavities following this technique represents a new approach to control coherent magnons, while the spin pumping voltage in a nanometer-sized Pt strip demonstrates to be a non-invasive local detector of the magnon resonance intensity.
