Oxidation in the system InNi observed with pac

The oxidation of111In implanted into Nickel was investigated with the PAC method. The samples heated in oxygen at 295–1223 K exhibit two fractions of oxidized In atoms, one clearly indentified as111InNiO. The temperature dependence of the Lamor frequency of111In in antiferromagnetic NiO was measured. The second fraction shows broadly distributed PAC parameters and is attributed to the trapping of interstitial oxygen at the In atom. The similarity between its quadrupole interaction parameters and those found for other fcc metals indicates the formation of similar InOx complexes by the same mechanism in all fcc metals.
