Polymorphism of the Co-Te nanophases in mechanochemical synthesis.

ABSTRACT: The mechanochemical synthesis of all cobalt tellurides' phases is demonstrated in this work. The samples had their structural, microstructural, and magnetic characterizations performed by X-ray powder diffraction, transmission electron microscopy, and magnetometry techniques. The initial atomic stoichiometries tested of Co₃₂Te₆₈ and Co₄₀Te₆₀ resulted in the synthesis of the γ-CoTe₂ Pnnm (marcasite), α-CoTe₂ Pa3̄ (pyrite), α-CoTe₂ P3̄m1 (CdI₂-like), and β-CoTe P6₃/mmc phases with different weight proportions in the sample. Modeling of the X-ray diffractograms employed conventional double-Voigt and crystallite shape-anisotropy DV approaches to show that
