(a) Schematic of the double-arm Larmor diffraction. Regions with different colours refer to different magnetic field directions, where blue refers to the main field inside the device, green arrows refer to the guide field (shown in (b)) between the two arms and red refers to the rotatable guide field on the two ends of the device. Please note that the arm in Fig. 1(b) now goes after the sample and this causes the sense of the triangles in the arm before the sample is different from Fig. 1(b), which means the calculation of the effective tilting angle for this arm using Eq. 8 will take the opposite sign.
