摘要
The phase equilibria in the Y-Mn-Sn and Dy-Mn-Sn ternary systems were studied at 770 K by means of X-ray and metallographic analyses in the whole concentration range. Both Y-Mn-Sn and Dy-Mn-Sn systems are characterized by formation of two ternary compounds RMn(6)Sn(6) (MgFe(6)Ge(6)-type, space group P6/mmm) and R(4)Mn(4)Sn(7) (Zr(4)Co(4)Ge(7)-type, space group I4/mmm). The disorder in Dy(4)Mn(4)Sn(7) compound was found by single crystal method. Compounds with the same type of structure were also found with Gd, Tb, Ho, Er, Tm (confirmed), Yb, and Lu and their lattice parameters were determined. (C) 2011 Elsevier B.V. All rights reserved.
