摘要

Single phase samples of .the R_6Pb_2Se_(11) (R = Y, Dy and Ho) compounds were obtained using high temperature synthesis. Crystal structure of Ho_6Pb_2Se_(11) (Y_6Pb_2Se_(11) type, space group Cmcm, Pearson symbol oC76, lattice parameters: a = 0.40603(7) nm, & = 1 .3397(3) nm, c = 3.7542(5) nm) was reinvestigated by means of X-ray single crystal diffraction and refined down to Rl = 0.0572. Magnetic properties of the R_6Pb_2Se_(11) compounds were studied in wide ranges of temperature and magnetic field. Dy_6Pb_2Se_(11) and Ho_6Pb_2Se_(11) were found to order antiferromagnetically at T_N = 2.2 and 2.4 K, respectively, whereas weak diamagnetism was established for Y_6Pb_2Se_(11).
