摘要：
The magnetic properties of a pseudo-1D system were examined by Fe-57 Mossbauer spectroscopy at various temperatures for Jamesonite, Fe2+ Pb4Sb6S14. The spectra above 20K are paramagnetic and those below 10K consist of two components: (i) a complex-split spectra with a large quadrupole split and small hyperfine field as the dominant component and (ii) a sextet with a large hyperfine field and very small quadrupole split. The hyper. ne parameters of the low-temperature spectra are discussed from the point of view of valence and spin state in Fe. (C) 2006 Elsevier B. V. All rights reserved.
