Fig. 5: Magnetic gradiometer and polar angle sensitivities.
From: Pulsed vector atomic magnetometer using an alternating fast-rotating field
The solid lines illustrate the sensitivities of the FRF vector magnetometer for the total magnetic field and the two transverse magnetic fields. The dashed line depicts the sensitivity of the magnetometer in scalar mode. The inset highlights the frequency response for bx and by. The polar angle sensitivities, applicable only to bx and by, are shown on the right-side y-axis and are calculated by dividing bx and by by the total static magnetic field, B0.
