摘要：
The influence of an applied MF on the SERS of Ag nanoparticles was investigated both experimentally and theoretically. The presence of a MF could lead to reducing electrons on the surface of Ag nanoparticles and a broadened energy gap, which could reduce surface plasma and charge transfer and then decrease the SERS intensity.
