摘要：
Complex oxides Ln(2)Mn(2/3)Re(4/3)O(7) (Ln = Y, Er) and Y2Zn2/3Re4/3O7 with a zirkelite structure and hexagonal unit cells (space group P3(1)21, z = 6) have been obtained. Static and dynamic magnetic susceptibility measurements show that these oxides possess spin-glass behavior at low temperatures. Valence combinations of cl-metals in the oxides are Mn2+(Zn2+)-Re5+. It is supposed that the examined specimens Ln(2)Mn(2/3)Re(4/3)O(7) (Ln = Y, Er) contain the second magnetic phase of an unknown composition. (C) 2009 Elsevier B.V. All rights reserved.
