Synthesis and characterization of ternary compound, Mn2SnTe4

Mn 2 SnTe 4 was synthesized by direct fusion using the anneal method. X-ray powder diffraction analysis indicated that this material crystallizes in the olivine-type structure, space group Pnma , Z = 4, with unit cell parameters: a = 14.020(2) Å, b = 8.147(1) Å, c = 6.607(1) Å, V = 754.7(2) Å 3 .

Zusammenfassung:Mn 2 SnTe 4 was synthesized by direct fusion using the anneal method. X-ray powder diffraction analysis indicated that this material crystallizes in the olivine-type structure, space group Pnma , Z = 4, with unit cell parameters: a = 14.020(2) Å, b = 8.147(1) Å, c = 6.607(1) Å, V = 754.7(2) Å 3 . The Rietveld refinement converged to the figures of merit, R p = 6.9%, R wp = 8.5%, R exp = 6.0%, χ 2 = 2.0 and S = 1.4.
