摘要：

Single crystals of the Cu3Fe0.5Se2 composition have been grown. The orthorhombic lattice parameters are found to be a = 8.169 angstrom, b = 8.238 angstrom, c = 12.052 angstrom, V = 811.15 angstrom(3), D-x = 6.23 g/cm(3), sp. gr. Pnma, Z = 8. The magnetic susceptibility is measured in the range 100 < T < 400 K at H = 2 T. It is established that a crystal transforms into the antiferromagnetic state below T-N = 350 K. The temperature dependences of the electrical conduction (sigma), thermal electromotive force (alpha), and thermal conduction (k) are measured in the range 80 < T < 400 K; the n value was calculated to be 5 x 10(19) cm(-1).
