Abstract

Exploiting the precession of a levitated magnetic particle in ultra-high vacuum, it is shown that ac magnetic fields smaller than a picotesla can be detected. It is also argued that this new AC magnetometer will have a large dynamic range of more than a millitesla and can be continuously tuned over several GHz. Such a magnetometer can be used as a receiver for electromagnetic waves.
