摘要：

The study of structural properties of quaternary Pb1-x-ySnxMnyTe alloys revealed that they crystallise in a cubic structure of NaCl-type for a wide region of manganese content (up to y = 0.16). It was found from X-ray measurements and microprobe analysis that Vegard's law is obeyed. The dependencies of the lattice constants on composition for Pb1-x-ySnxMny, Pb1-yMnyTe and Sn1-yMnyTe were used to extract the lattice parameter of NaCl-type MnTe phase by extrapolation. The experimental data were also used to obtain an improved estimate of the covalent octahedral radius for Mn. (C) 1999 Elsevier Science B.V. All rights reserved.
