Abstract

Abstract Magnetic susceptibilities of Ba 2FeS 3, Ba 2CoS 3, and Ba 2MnS 3 show rounded maxima at 130, 125, and 100 K, respectively, which are due to quasi-one-dimensional antiferromagnetic short-range ordering. Intrachain interactions, J k , are estimated to be −20, −15, and −12 K, respectively. 57Fe Mössbauer spectra of Ba 2FeS 3 and 57Fe-doped Ba 2CoS 3 and Ba 2MnS 3 at 4.2 K show long-range antiferromagnetic ordering, due to the interchain interaction. The profile of Mössbauer spectra at 4.2 K is analyzed based on the coexistence of magnetic hyperfine and quadrupole interactions, and magnetic hyperfine fields at 4.2 K are estimated to be 36, 29, and 59 kOe, respectively.
