Abstract :
The synthesis, structure, and magnetic properties of lithium dibarium calcium oxide fluoride disulfide are reported. LaCa0.143 (4)O0.857 (4)F0.143 (4)Bi0.857 (4)S2 crystallizes in the tetragonal space group P4/nmm. The structure exhibits disorder of the Ca2+ and Bi3+ cations, and the O2− and F− anions. The structure is composed of a stacking of [(O,F)2La2] layers and double [(Bi,Ca)S2] layers. Magnetic property measurements indicate a very small magnetization at 300 K and the existence of weak ferromagnetism at 2 K.
