Crystal Structure of the New Compound TbCo0.67Ga1.33

Abstract

A new ternary compound TbCo0.67Ga1.33 was discovered and studied by means of X-ray powder diffraction technique. The crystal structure of the new compound was refined by using Rietveld method from X-ray powder diffraction data. This compound crystallizes in the orthorhombic with the CeCu2 structure type( space group Imma, a = 0.43384(6) nm, b = 0.70193(1) nm, c = 0.75617(1) nm, Z = 4, and Dcalc = 8.512 g/cm3 ). The Rietveld refinement results were Rp = 0.0996, Rwp = 0.1277.
