Microcavity optomechanical magnetometry with picotesla-sensitivity
A new microcavity magnetometry with FeGaB thin film achieves 1.68 pT/Hz<sup>1/2</sup> sensitivity, which is two orders of magnitude improvement over previous work. Corona current detection has been demonstrated using this magnetometer.
