Fig. 2: Miscibility of the A-site cations in the AMnSb2 system.
From: High-entropy engineering of the crystal and electronic structures in a Dirac material
a Diagram summarizing whether ten possible binary mixings of A-site cations yield a homogeneous solid solution system (\(A,{A}^{{\prime} }\))MnSb2. Approximate values of Shannon’s eight-coordinate ionic radii are shown for the five A-site cations. Sr2+ and Eu2+, and Ca2+ and Yb2+ have almost identical ionic radii to each other. EDS composition mapping for the A-site elements collected for b (Ba,Ca)MnSb2, c (Ba,Yb)MnSb2, and d A5MnSb2 samples.
