Abstract
The new ternary transition metal telluride CrAuTe4 has been discovered through solid-state reaction of the elements. The crystal structure is solved in the monoclinic space group P2/m (No. 10) with lattice parameters a=5.4774(7) Å, b=4.0169(6) Å, c=7.3692(13) Å, and β=90.604(10)°. The structure is related to that of the binary compound AuTe2, and a derivation of the structure of CrAuTe4 from AuTe2 is shown. Measurements of the thermopower, thermal conductivity, electrical resistivity, and magnetic susceptibility are presented. The compound undergoes a paramagnetic to antiferromagnetic transition at 255 K.
