Null-field alignment-based magnetometry schemes. (a) Hanle effect on atomic alignment: a cell containing helium, with the metastable state populated by a high-frequency discharge, is subject to a linearly-polarized light-beam, with light electric field \(\vec{E}_{p}\). This beam is photodetected after the cell. (b) Parametric resonance magnetometer based on atomic alignment: in the addition to the elements of the former scheme, this one includes two RF fields set along the axes orthogonal to \(\vec{E}_{p}\). (c) Experimental setup which allows an implementation of both schemes
