Crystal Structures and Magnetic Properties of Quaternary Manganese Sulfides, BaLn2MnS5 (Ln=La, Ce, and Pr)

Crystal Structures and Magnetic Properties of New Quaternary Sulfides BaLn2MS5 (Ln=La, Ce, Pr, Nd; M=Co, Zn) and BaNd2MnS5

“…In these compounds, only the lanthanide ions are magnetic. The e!ective magnetic moments per mole of the lanthanide ion are determined to be 2.551 (2) for BaCe ZnS , 3.666(2) for BaPr ZnS , and 3.655 (1) for BaNd ZnS by applying the Curie}Weiss law ( "C/(¹! )) to the reciprocal susceptibility vs temperature curve in the high temperature region (150 K4¹4300 K).…”

“…Its electrical properties showed an n-type semiconductivity. Recently, we investigated the crystal structures and magnetic properties of Ba¸n MnS (¸n"La, Ce, and Pr) (2). From their electron paramagnetic resonance spectra, magnetic susceptibilities, and speci"c heats, the Mn ions were found to be in the S state and showed the antiferromagnetic ordering at 58.5 K for BaLa MnS , 62 K for BaCe MnS , and 64.5 K for BaPr MnS .…”

“…Syntheses and crystal structures of a new series of quaternary sulfides, BaLn 2 TS 5 (Ln ~La-Nd, Sm; T ~Mn, Co, Fe, Zn), have been reported in recent years. [1][2][3][4] These compounds crystallize in a tetragonal structure with space group I4/mcm. The schematic crystal structure of BaLn 2 TS 5 is illustrated in Fig.…”
