Abstract	A metallic Fe specimen, implanted with 111In, was oxidized and subsequently annealed in a high vacuum for PAC spectroscopy. This treatment gave rise to a huge PAC signal. The magnitude of the hyperfine field was found to be one third of that in metallic Fe. CEMS on an enriched Fe foil given exactly the same treatment has revealed that a maghemite phase (γ-Fe2O3) is formed right after the oxidation treatment and a magnetite phase (Fe3O4) after the vacuum annealing. 111In in the magnetite phase was found to give rise to a PAC signal with large amplitude. PAC spectroscopy in an external magnetic field has revealed that the site of 111In is the tetrahedral site of the magnetite with the hyperfine field of +12 T, which is in excellent agreement with those in the ferrites. The present method of oxidation of metallic Fe with nuclear probes in it is quite useful for the study of oxidation processes. Also, it provides us with a simple means to prepare ferrite specimens incorporated with nuclear probes.
