Abstract
Section titled āAbstractāThe diamond Nitrogen-Vacancy (NV) center ensemble magnetometer is a new type of magnetometer with the characteristics of high sensitivity and small spatial resolution that can be used at room temperature. In order to solve the problem of miniaturization of this new magnetometer, a set of miniaturized diamond NV color ensemble magnetometer system based on fiber coupling has been built with multi-mode fibers, a piece of diamond with large area, microwave antenna with high radiation efficiency, and other components. Calibration of this magnetometer has been conducted to test its magnetic field sensitivity. The experimental results show that although the diamond NV center ensemble magnetometer system has been miniaturized, its sensitivity is still greater than 13uT.
