Resumen
This paper presents a Mössbauer study of isomer shift, hyperfine field and electric field gradient for γ′-Fe4N. These data are analyzed with the aid of an ab-initio electronic structure calculation using the self-consistent (LMTO) method. The calculated isomer shift and hyperfine field are in good agreement with the experimental results. The present analysis sheds some light into the relevance of previous models for the electronic structure of this system. © 1992. 111 1-2 95 104 Juza, (1966) Advances in Inorganic Chemistry and Radiochemistry, 9, p. 81. , H.J.
