摘要: Abstract Perovskite metal oxide (LiNbO3) nanomaterial is explored as a magneto-optic sensor. The electromagnetic interaction described by modulation associated with vacancy-induced room temperature ferromagnetism. guiding and propagation through single mode fiber (SMF) via the excitation of core modes material-mediated cavity further modulated external magnetic field. sensitivity resolution sensor are found to be 186 p.m./mT 0.51 Oe, respectively. structure material integrated optical design resulting in Fabry-Perrot interferometer (FPI), implemented an extrinsic sensor, sensing mechanism elaborated.
