Journal ArticleDOI
Accumulation and recovery of defects in ion-irradiated nanocrystalline gold
TL;DR: In this article, the effects of 60 MeV 12 C ion irradiation on nanocrystalline gold (nano-Au) were studied and the experimental results showed that the irradiation-produced defects in nano-AU are thermally unstable because of the existence of a large volume fraction of grain boundaries.
Journal ArticleDOI
Study of heavy-ion induced modifications in BaF2 and LaF3 single crystals
A.S. El-Said,M. Cranney,Norito Ishikawa,Akihiro Iwase,R. Neumann,K. Schwartz,Marcel Toulemonde,Christina Trautmann +7 more
TL;DR: BaF2 and LaF3 single crystals were irradiated with different ions from Ne to U having energies between 1.4 and 13.3 MeV/u and were subsequently analyzed with scanning force microscopy (SFM), optical spectroscopy and surface profilometry.
Journal ArticleDOI
Atomic structure and disordering induced by 350 MeV Au ions in MgAl2O4
TL;DR: In this article, the structure of ion tracks was found to consist of three concentric circle structures: the defective core region (∼2nm in diameter), strained region ( ∼ 5nm) and cation disordered region (10-12nm).
Journal ArticleDOI
Anomalous shift of Curie temperature in iron–nickel Invar alloys by high-energy heavy ion irradiation
Akihiro Iwase,Y. Hamatani,Y. Hamatani,Y. Mukumoto,Norito Ishikawa,Y. Chimi,T. Kambara,C. Müller,R. Neumann,F. Ono +9 more
TL;DR: In this paper, the Curie temperature for the irradiated region increases with increasing the ion fluence, implying that it is attributed to ion-induced high-density electronic excitation.
Journal ArticleDOI
Swift heavy ion induced magnetic phase transition of Fe–Rh alloy
TL;DR: In this paper, the effects of swift heavy ion irradiation on structure and magnetic properties of Fe-50at alloys were investigated using superconducting quantum interference device (SQUID) and X-ray diffractometer (XRD).
