Abstract We have fabricated Mn‐doped Bi 2 Te 3 and Sb 2 Te 3 single crystals by the vertical gradient solidification method. The compositions and crystal structures of Bi 2− x Mn x Te 3 and Sb 2− x Mn x Te 3 were determined using Electron Probe Micro‐Analyzer (EPMA) and powder X‐ray diffraction (XRD) patterns, respectively. Both crystal structures were rhombohedral with smaller lattice constants because of the smaller atomic radius of Mn than those of Bi and Sb. Based on the magnetization measurements, Mn‐doped Bi 2 Te 3 and Sb 2 Te 3 compounds have ferromagnetic ordering at T C = 10 and 17 K, respectively. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
