The nature of the C-defects in nickel and their r�le in the interpretation of radiation damage in metals

Magnetic Hyperfine Interaction of a Cubic Defect in α-Iron

“…It can be produced by implantation, by particle irradiation but also by cold-working of Ni. The structure of the cubic defect in fcc Ni is discussed on the basis of two models: (1) the In probes are at an interstitial site which is the centre of a tetrahedron consisting of four nearest neighbour vacancies [2] or (2) the cubic defects are In probes on a tetrahedrally coordinated interstitial position in the fcc lattice [1]. For both configurations mobile vacancies or interstitials in the vicinity of specimen surfaces are necessary.…”

“…In connection with a certain lattice damage and with 111 In( 111 Cd) as probe, a defect with cubic symmetry was identified and intensively investigated. The structure of this defect is controversially discussed because of its fundamental importance for the interpretation of recovery stage III [1,2]. Magnetic hyperfine fields at 111 Cd probes on different sites of single crystalline Ni surfaces were thoroughly investigated in [6].…”
