Magnonics, an emerging research field that uses the quanta of spin waves as data carriers, has the potential to dominate the post-CMOS era owing to its intrinsic property of ultra-low-power operation. Spin waves can be manipulated by a wide range of parameters; thus they are suitable for sensing applications in a wide range of physical fields. In this study, we have reported an ingenious method to control the spin-wave propagation by forming a magnonic resonator using CoFeB/Y₃Fe₅O₁₂ bilayer. In the subsequent step, this resonator structure has been used to design a highly sensitive, simple structure, and ultra-low power magnetic sensor.
