Abstract
A new compound, CuIr2Te4, has been successfully synthesized. The X-ray expe riments indicate that this new compound has defect NiAs structure of trigon al symmetry with space group P (3) over bar ml. The resistivity rho and the magnetic susceptibility chi of CuIr2Te4 have revealed the existence of hum p-shaped maxima around 250 K on heating, 190 K on cooling, exhibiting the t emperature hysteresis. This anomalous behavior originates presumably from a charge-density wave formation with the partial gap at the Fermi level. (C) 1998 Elsevier Science Ltd. All rights reserved.
