基于Au/FexCo1-x结构的磁光表面等离子体共振（MOSPR）传感器的性能研究
Study on the sensing performance of Au/Au/FexCo1-xstructure based on magneto-optic Surface plasmon resonance
近年来，MOSPR折射率传感器因其高灵敏度和检测限受到了广泛的关注。我们使用FexCo1-x作为MOSPR器件中的铁磁层，并对不同成分的FexCo1-x在Au/FexCo1-x结构中的传感性能进行了研究，并对MOSPR器件的灵敏度进行优化。根据4×4转移矩阵法与实验验证，我们发现各成分下Au/FexCo1-x的最优灵敏度与该成分FexCo1-x磁光效应的强弱有关，且所有结构中Au/Fe0.7Co0.3结构具有最优的传感灵敏度，证明FexCo1-x可作为一种强磁光效应金属薄膜应用于高灵敏度MOSPR传感器。
In recent years, MOSPR refraction index sensor has been widely studied for its high sensitivity and low limit of detection(LOD). Here we use FexCo1-x as the ferromagnetic layer in MOSPR structures and investigated the sensing performance of Au/FexCo1-x MOSPR transducers with different FexCo1-x components. Based on 4×4 transfer matrix method and experimental verification, we find that the highest sensitivity of Au/FexCo1-x bilayer transducer is clearly correlated to FexCo1-x's MO response. In all structures, Au/Fe0.7Co0.3 shows the best sensing performance owing to its highest MO response, suggesting FexCo1-x as a promising candidate for ultrasensitive MOSPR sensors.
