Data for: "Enhanced material defect imaging with a radio-frequency atomic magnetometer"

Fig2: Simulated amplitude data for by and bz magnetic field components. Fig3: Simulated amplitude and phase data for measured signal as by and bz components of the primary field compensation is varied. Fig4: Excel sheet containing data points corresponding to the amplitude and phase contrast as the compensation coil position is varied. Fig5: 2D amplitude and phase images recorded with different primary field compensation. 1D simulated data is also provided. Fig7: 2D amplitude for different compensation geometries. Fig8: 2D amplitude and phase data which is plotted and used to make a 2D vector graph of the secondary field.
