ABSTRACT:
A differential resonance magnetometer, which includes a reference assembly and at least one measurement assembly. A polarization current is produced by the reference assembly is the same as a polarization current used in the measurement assembly. A feedback signal produced by the measurement assembly directly gives a difference between fields in the reference and measurement assemblies. Such a device may find particular application to magnetometry.
