Investigation of Nanocrystalline Materials Using Radioactive Isotopes
-
Th. Wichert
The potential of detecting the hyperfine interaction at the nuclear site of radioactive isotopes for the investigation of nanocrystalline (nc) materials is discussed. The subject is illustrated with help of different examples for characterizing nc samples. Using the perturbed γγ angular correlation technique (PAC) for detecting the hyperfine interaction at the site of the radioactive probe 111In/111Cd experiments regarding the doping of nc semiconductors ZnO and InP, the shift of the Néel temperature in nc antiferromagnetic NiO, the structure of grain boundaries in Ni, and the homogeneity of nc Ni-Cu alloys are presented. The resulting information is compared with that obtained by Mössbauer spectroscopy and by standard techniques used in materials science.
