Local atomic disordering by high-density electronic excitation in spinel crystal
- 1. Kyushu Univ., Dept. of Applied Quantum Physics and Nuclear Engineering, Fukuoka (Japan)
Description
The atomic disordering in magnesium aluminate spinel irradiated with 200 MeV Xe14+ or 350 MeV Au28+ was examined quantitatively by electron channeling X-ray spectroscopy of analytical TEM. The structure of ion tracks keeps spinel structure, but it was indicated that cation were randomly disordered. The radius of the disordered region by the single swift heavy ion was estimated about 6.0 nm, which was larger than the radius of ion tracks estimated by TEM observation. (author)
