Abstract:

A brief introduction is given to the basic ideas of ion implantation and the methods of nuclear orientation and NMR on oriented nuclei. This outline review discusses experiments carried out using these methods to describe the lattice sites and hyperfine interactions of ions which have no equilibrium solubility in iron, when introduced into the iron lattice by implantation. Examples are given of substitutional and vacancy associated sites. The paper ends with a discussion of two problematic systems, Cs Fe and Fr Fe, under current investigation. © 1994 J.C.

Abstract:

Hyperfine interactions at Ce sites of CeNi2Al5 and CeNiSn single crystals were investigated by means of the low-temperature nuclear orientation of the 141Ce isotope. From the temperature dependence of γ-ray anisotropies the hyperfine fields at Ce nuclei in CeNi2Al5 and CeNiSn were deduced as 92 (±6) T and <6 T, respectively. © 1993.
