Abstract
Polycrystalline samples (weight ~ 1g) o f Cu2GeTe4 and Cu2SnTe4alloys were prepared by the usual melt and anneal method and the products characterized by X-Ray Diffraction (XRD) and Differential Thermal Analysis (DTA) techniques. Cu2GeTe4and Cu2SnTe4crystallize in an orthorhombic structure (s.g. Imm2; No 44) with lattice parameters a=5.9281(4) Å, b=4.2211(6) Å, c=12.645(5)Å and a=6.0375(6) Å, b= 4.2706 (3) Å, c=12.844(1)Å, respectively. Both alloys show two thermal transitions: 762 and 636K upon heating and; 700 and 578K upon cooling for Cu2GeTe4; 702 and 636K upon heating and; 650 and 590K upon cooling for Cu2SnTe4.
