用{sup 57}Fe穆斯堡尔谱研究了脆硫锑铅矿Fe{sup 2+}Pb{sub 4}Sb{sub 6}S{sub 14}在不同温度下的赝一维体系的磁性。20 K以上的光谱是顺磁性的，而10 K以下的光谱由两个分量组成：（i）具有大四极分裂和小超精细场的复合分裂光谱作为主要分量;（ii）具有大超精细场和非常小四极分裂的六重谱。从Fe的价态和自旋态的角度讨论了低温光谱的超精细参数。
The magnetic properties of a pseudo-1D system were examined by {sup 57}Fe Moessbauer spectroscopy at various temperatures for Jamesonite, Fe{sup 2+}Pb{sub 4}Sb{sub 6}S{sub 14}. The spectra above 20 K are paramagnetic and those below 10 K 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 hyperfine parameters of the low-temperature spectra are discussed from the point of view of valence and spin state in Fe.
