Figure 4
(a) XRD scan along the (00)-CTR of the reference sample. Since nothing can be seen in the range L < 1.5 except for the substrate reflection, this is not shown. (b) L scan along the $[(22)_{\rm cub}]$ -CTR of Fe₃O₄(001) of the reference sample (H ≈ K ≈ 0.93, cf. Fig. 2

). Here, the sharp outliers at L = 1 and L = 2 are due to diffuse scattering close to very intense substrate Bragg peaks being close to the measured Fe₃O₄ CTR. (c) Schematic sketch of the reflections expected on and near the $[(22)_{\rm cub}]$ -CTR of completely relaxed Fe₃O₄(001) and Fe₃O₄(111).
