(a) Schematic structure of the phase-separated Ga\(\delta \)FeN layers. (b) Detail of a nanocrystal and its surroundings with corresponding plan-view TEM, SADP and cross-section TEM (XTEM) image. (c) Radial 2\(\theta \)-\(\omega \) HRXRD scans of the investigated samples. (d) Detail of the scan in (c) showing the shift of the (200) \(\gamma '\)-\(\hbox {Ga}_y \hbox {Fe}_{4-y}\)N diffraction peak to larger angles, i.e smaller lattice parameter along the c-growth direction, with decreasing normalized Ga flow.
