To reduce Hg high pressure related to the high-temperature synthesis reaction between the components in elemental form, Hg_1-xMn_xTe bulk crystals were produced by ta two-step procedure including (I) the alloy synthesis using HgTe crystals grown by the cold travelling heater method and elemental Mn and Te to complete the desired composition, followed by (II) the Bridgman growth. The growth was carried out at temperature in the range of 700-850 deg C and rate of 1 mm/h. The Hg_1-xMn_xTe crystals have been characterised by X-ray diffractometry, energy dispersive X-ray analysis, Fourier transformed infrared spectroscopy and Hall effect techniques. Although the distribution coefficient of Mn was found to be in the range of 3-3.5 in the first-to-freeze region, the crystals show a good axial composition uniformity throughout more than a half of the total length. The lattice parameter of Hg_1-xMn_xTe is reported for the studied composition range x=0-0.15. direct c 1999 Elsevier Science B.V. All rights reserved.
