Post‐annealing studies in different atmospheres combined with high resolution x‐ray studies on epitaxial ZnO and Zn 1–x Co x O films revealed that the c ‐axis lattice parameter decreases when interstitial zinc is removed from ZnO. The ‘ c ' parameter change reverses sign when samples are re‐annealed in a Zn‐rich atmosphere. Stronger ferromagnetism occurs in Zn 1–x Co x O film for higher ‘c' parameters and hence higher Zn interstitial concentrations.
