AB In this study, we investigate the relationships among film growth conditions, crystalline microstructure, and magnetic properties of epitaxial yttrium iron garnet (Y3Fe5O12, YIG) thin films, deposited on gallium gadolinium garnet (Ga3Gd5O12, GGG). A direct correlation was observed between the residual epitaxial strain, bulk magnetic properties like effective magnetization and magnetic damping, and the performance of spin-wave transmission devices based on these films. This correlation offers a pathway for a simplified, rapid assessment of YIG film quality, avoiding the need for complex time-consuming characterization techniques. In addition, we report a comprehensive investigation into the influence of pulsed-laser deposition parameters, including deposition temperature, pressure, laser fluence, frequency, and annealing conditions. Through systematic deposition optimization, state-of-the-art YIG films exhibiting ultralow magnetic damping could be obtained, which is critical for high-performance spintronic applications
