- Аннотация: We studied the effect of Mn on the structure and properties of Cd3-xMnxAs2 crystals with x =0-0.24, synthesized by direct fusion of high-purity elements. Obtained X-ray diffraction patterssuggest that the incorporation of Mn promotes a structural phase transition from primary α-Cd3As2(x = 0) phase to the α''– Cd3As2 (x = 0.24) phase, while at intermediate compositions both phasescan coexist. In addition, the increase of Mn content results in the decrease of lattice cell parameters,which effectively saturates for x > 0.13. Microstructural, calorimetric and magnetometry studiessuggest that at high Mn content (x = 0.24) secondary MnAs phase appears. Using obtained results,we estimated the solubility limit of Mn in Cd3As2 as x ~ 0.13, which corresponds to the formationof ternary Cd3-xMnxAs2 compound where Cd atoms are partially substituted by Mn. Formation ofternary compound was also suggested by the results for Cd3As2 + MnAs composite systems, wherewe also observed the presence of CdAs2 phase, which is a byproduct of corresponding reaction.Additional studies suggested that the CdAs2 phase formation in composite system can be preventedif one uses the Cd3-xMnxAs2 compound instead of pure Cd3As2 as a matrix material.
