Ion irradiation-induced crystal structure changes in inverse spinel MgIn2O4
چکیده انگلیسی

400 keV Ne and 200 keV He ion irradiations were performed on fully inverse MgIn2O4 samples at cryogenic temperature (~ 77 K), in order to examine the influence of radiation-induced cation disordering on crystal structure. In the case of MgIn2O4 samples irradiated with Ne ions to a peak displacement damage dose of 4 displacements per atom (dpa), a spinel-to-rocksalt phase transformation was observed. By contrast, for MgIn2O4 samples irradiated with He ions to a peak displacement damage dose of 5 dpa, the only observed structural effect involved cation rearrangements from an inverse to a “random” spinel structure.
