  • Experimental evidence of the changes of the short range order (SRO) in amorphous alloys due to high energy deposition in electronic processes related to the slowing down of swift heavy ions is presented. Modification of the local structure was studied by the specialized {open_quotes}rf-Moessbauer{close_quotes} technique in amorphous Fe{sub 40}Ni{sub 35}Si{sub 10}B{sub 15}, Fe{sub 73.5}Nb{sub 3}Cu{sub 1}Si{sub 13.5}B{sub 9}, Fe{sub 73.5}Nb{sub 4.5}Cr{sub 5}Cu{sub 1}B{sub 16}, and Fe{sub 80.5}Nb{sub 7}B{sub 12.5} alloys irradiated at low temperature with 6 GeV Pb ions. The changes of SRO were studied as a function of ion fluence (from 1{times}10{sup 11} to 2.4{times}10{sup 13}ions/cm{sup 2}) and electronicmore » energy deposition rate for the amorphous Fe{sub 40}Ni{sub 35}Si{sub 10}B{sub 15} alloy. The effects observed were interpreted in relation to the anisotropic growth of the amorphous samples. A novel effect consisting of partial surface crystallization induced by swift heavy ion irradiation was observed in the Fe{sub 90}Zr{sub 7}B{sub 3} alloy by conversion electron Moessbauer spectroscopy. {copyright} 2001 American Institute of Physics.« less
  • Swift xenon ions (1.43 GeV) were used to systematically investigate the radiation response of pyrochlores in the Gd2Zr2-xTixO7 binary in the electronic energy loss regime. Ion-induced structural modifications were characterized by synchrotron x-ray diffraction, Raman spectroscopy and transmission electron microscopy. In general, individual ion tracks consist of amorphous domains (in the core of the track) and are surrounded by a crystalline, but disordered structure (track shell), and finally, by a defect-rich region (track halo). The size and structure of these concentric regions, which form dynamically in single ion tracks, depend on the chemical composition. The overall extent of the radiationmore » damage strongly increases with Ti-content, and this confirms the enhanced radiation stability of Zr-rich pyrochlore, even within single swift heavy ion tracks.« less
