Abstract

Mössbauer spectroscopy is used to study the state of iron atoms in samples with a composition of CuCr1−x Fe x S2 (x = 0.01–0.30). It is shown that at x ≤ 0.02 samples are solid solutions in which iron atoms have an oxidation number of 3+ and replace chromium atoms in octahedral sites. When the iron concentration increases, the second phase — chalcopyrite CuFeS2 — forms along with the solid solution. The relative iron concentration in this phase increases from 11% at x = 0.03 to 52% at x = 0.30.
