Electronic transport and magnetic properties of a new NICKEL ANTIMONIDE (cas 12503-49-0) telluride, Ni2SbTe2

Add time:08/11/2019    Source:sciencedirect.com

The mixed anion compound, Ni2SbTe2, has been prepared from the elements in a potassium iodide flux. The crystal structure is solved in the hexagonal space group P63/mmc (no. 194) with lattice parameters a=b=3.9030(9) Å and c=15.634(3) Å. Sb and Te occupy crystallographically distinct anion sites within the crystal structure. The Seebeck coefficient, electrical resistivity, and magnetic susceptibility have been measured for the title compound, and shows typical metallic behavior. Extended Hückel band structure calculations also predict metallic behavior in bands dominated by Ni and Te orbital contributions.
