Abstract

This disclosure relates to the field of zero-field paramagnetic resonance magnetometer (ZF-PRM). A sensitive ZF-PRM capable of measuring magnetic field in three orthogonal directions simultaneously and method of measuring magnetic field in three orthogonal directions is described. The ZF-PRM provides three independent output signals proportional to the three orthogonal vector components of the magnetic field using a single vapor cell, thus reducing complexity and cost of the magnetometer. Because all three magnetic components are measured at substantially the same location at the same time, the accuracy of data is greatly increased.
