英文摘要	The mixed-metal sulfide compound with the formula Ba2Fe0.6V1.4S6 was successfully synthesized via solid-state reaction. Ba2Fe0.6V1.4S6 has a quasi-one-dimensional structure and crystallizes in the hexagonal space group P6(3)/mmc. The structure is composed of face-sharing anion octahedron [MS6](8-) (M = V or Fe) units to construct infinite chains along the c axis, in which the Fe atoms randomly occupy the V sites. The Ba2+ ions reside between adjacent chains. Magnetic susceptibility measurements reveal a transition between paramagnetism and ferromagnetism around 25 K. The small polaron hopping (SPH) conduction behavior has been observed in the higher temperature region (75-300 K), while in the lower temperature region (25-74 K), the resistivity features a variable range hopping mechanism (VRH). The analysis of density of states indicates that Fe-3d(z2) and S-3p states mainly dominate the valence band maximum, while Fe-3d(z2) states contribute significantly to the magnetic susceptibility.; "Strategic Priority Research Program (B)" of the Chinese Academy of Sciences [XDB04040200]; CAS Center for Excellence in Superconducting Electronics; National Key Research and Development Program [2016YFB0901600]; NSF of China [11404358, 51402341]; Science and Technology Commission of Shanghai [13JC1405700, 14520722000]; SCI(E); ARTICLE; 14; 8302-8310; 56
