Abstract
A series of quaternary metal sulfides of the general formula La3MM'S7 (M = Mn, Fe, Co; M'= Al and M = Mg, Mn, Fe, Co, Ni; M' = Fe) consisting of linear chains of face shared MS6 octahedra and isolated M'S4 tetrahedra has been prepared and studied. The aluminium compounds La3MAlS7 (M = Mn, Fe, Co) exhibit linear chain antiferromagnetism. Magnetic behavior of other La3MFeS7 sulfides has been examined in detail. The magnetic susceptibility of La3MgFeS7 shows that tetrahedral site Fe3+ undergoes a transition from S=5/2 to S = 2 spin state around 150 K.
