Abstract

MÖSSBAUER effect and X-ray diffraction measurements have shown that thin lamellae of the Cape York and Toluca meteorites contain the ordered phase Fe–Ni (50–50%) with the structure L10 (refs 1–3). The bulk of these meteorites consists mainly of body centred cubic (b.c.c.) iron–nickel α-phase alloy. We report here Mössbauer spectra, electron microprobes and X-ray measurements which show that in contrast to this, the bulk of the Ni-rich (≈35%) Santa Catharina Ataxite consists of up to 50% Fe–Ni superstructure4.
