Abstract
Spin waves offer a promising platform for novel spintronics and hybrid quantum systems, enabling information transduction over device-length scales with low power loss. To control their amplitude and transmission properties, effective structures such as Bragg reflectors are important. In this work, we demonstrate magnetic Bragg reflectors composed of periodic Ni strip lines fabricated on Yttrium Iron Garnet (YIG) thin films. Through transmission measurements of \({S}_{21}\) under varying magnetic fields, we identify wavenumbers of magnetostatic surface wave (MSSW) modes that satisfy Bragg scattering conditions. These results suggest that magnetic Bragg reflectors are effective candidates as filters and cavities for spin waves, with potential applications in spintronics and hybrid quantum systems.
