✦ Synopsis

molybdenum

Chevrel phases containing rare-earth atoms (REMotX8 ; X = S, Se) are model systems which can present at the same time, phenomena of superconductivity and long-range magnetic interactions. We have recently developed a new crystal growth method specific to the selenides series, which was applied to RE = Gd, Dy, He, Er and Yb. We present results obtained on single crystals of GdMo6Se8 and DyMo6Ses. A discussion of the crystal growth method and of the ternary phase relations is done, and results are compared to those obtained for the binary isostruetuml compound Mo3Se4.
