标题： Optomechanical magnetometry with a macroscopic resonator

摘要： 我们展示了一种基于晶体耳语画廊模式谐振器的厘米尺度光机械磁强计。 谐振器的大尺寸使得在赫兹到千赫兹频率范围内可以实现高磁场灵敏度。 报告的峰值灵敏度为每根赫兹131皮特斯拉，在磁屏蔽非低温环境中使用低于100微瓦的光功率。 通过进一步优化激光噪声和谐振器的物理结构，未来设备可能达到飞特斯拉范围的灵敏度，从而适用于高性能磁测量。 显示英文摘要

摘要： We demonstrate a centimeter-scale optomechanical magnetometer based on a crystalline whispering gallery mode resonator. The large size of the resonator allows high magnetic field sensitivity to be achieved in the hertz to kilohertz frequency range. A peak sensitivity of 131 pT per root Hz is reported, in a magnetically unshielded non-cryogenic environment and using optical power levels beneath 100 microWatt. Femtotesla range sensitivity may be possible in future devices with further optimization of laser noise and the physical structure of the resonator, allowing applications in high-performance magnetometry.
