Diffusion measurements carried out in this work, reveal that N self-diffusion is the swiftest in Co4N compared to other transition metal nitrides or even the mononitride CoN. By the application of a high substrate temperature (Ts) growth or thermal annealing temperature (Ta); N diffuses out from the fcc-Co4N above 573 K leaving behind a high purity fcc-Co phase. Generally, Co grows in a hcp structure and a (partial) hcp to fcc-Co transformation takes place around 700 K or above 70 GPa.
