Synthesis and study of Sr-substituted misfit layer sulfides
Two series of [(Ln1/3Sr2/3S)1.15] 1.15NbS2 (1.5Q/1H) and (Ln1- Sr S) 1+ NbS2 (1Q/1H) misfit layer sulfides have been synthesised and studied by X-ray powder and single crystal diffraction, EDX-analysis and magnetic measurements. For the early lanthanides (Ln = La, Ce) only the (Ln1- Sr S)1+ NbS2 (< 0.40-0.45, = 0.15-0.17) compounds were formed whereas for late lanthanides (Ln = Pr, Nd, Sm, Gd-Er,
