(a) Relative positions of axis \(A\) (clear-blue), \(\bar{A}\) (dark-blue), \(B\) (clear-magenta), \(\bar{B}\) (dark-magenta). The motion of the magnetization in between LG4 blocks (\(A\bar{A}\bar{B} B\)) is shown in purple. This evolution is described as a rotation in the plane (in yellow) perpendicular to the \(C\) axis in accordance with the effective Hamiltonian in Eq. (4) for a single \(\delta _i^*\). (b) (Top) Magnetization rotations during each of the four RF drivings. (Bottom) Projection of the magnetization onto \(\hat{z}\) as it rotates during a full LG4 block. This projection determines the magnetic signal for the NV ensemble sensor.
