The results of thermograph, XRD and microstructural study, and the electrical properties of the GaSb-FeGa1.3 and GaSb-CoGa1.3 artificial-anisotropic semiconductor eutectic composites have been made at the temperature range of 80-450K. The composites are prepared by the vertical Bridgeman method at 1 mm/min of the movement rate of the of crystallization front. The character of these composites are the presence of uniform distribution of the FeGa1.3 and CoGa1,3 metal inclusions in the GaSb matrix with length of 20-150, 5-20 μm, respectively and with diameter of 0,5 - 1 μm.. Composites have been p-type conductivity with charge carrier’s concentration at room temperature about of 1.2x1018cm-3 and 1.8x1018cm-3, respectively. On the base of the derivatographic studies have been determined the initial and final temperatures of melting, with respect to heat and entropy for eutectic composites. XRD analyses was carried out by the difractometer “Advance D8”at the 210, 300, 390, 420K temperature. It was shown that the structural change are not appear with the temperature. The analysis of the XRD specters by using the TOPAZ and EVA programs have been shown that the 97% part of system consists from of the matrix GaSb and the 3% part from of the second phase. Microstructure and morphology of the eutectic composites were investigated by the scanning electron microscope (SEM) PhilipsTM model with the prefix of X-ray spectroscope (EDX) EDAXTM model. The elemental compositions on the matrix, inclusions and interphase zone have been determined. It is shown that the presence of metal inclusions leads to the anisotropy of electrical conductivity and Hall effect. The calculation of the electrical conductivity was carried out in the framework of the effective media theory. The electrical conductivity of matrix, inclusions and interphase zones taken into account in the calculations of the total conductivity. It was shown that the roll of interphase zone is the essential factor in the short-circuiting action by inclusions leading to the anisotropy on the electrical conductivity.
