摘要：

Several Ln2O3-ReO2 systems (Ln = Nd, Sm, Gd, Dy, Er, Yb and Y) have been studied. New phases have been found and are characterized crystal-chemically. Tetragonal phases of the types Ln2ReO5 and Ln2ReO5.25 are described where Ln = Nd, Sm, and Gd. Other compounds near the Ln2ReO5 stoichiometry (Ln = Gd, Dy, Er, Yb, Y) appear to be monoclinic. In three systems (Ln = Dy, Er, Y) fluorite-like phases have been found. Magnetic susceptibility measurements were carried out for several of the new phases. All were found to be paramagnetic within the temperature range investigated (77°K to 373°K). © 1969.
