Magnetic Phase Separation in the Oxypnictide Sr₂Cr_1.85Mn_1.15As₂O₂.

ABSTRACT: Layered Sr₂M₃As₂O₂-type oxypnictides are composed of tetrahedral M₂Pn₂ and square planar MO₂ layers, the building blocks of iron-based and cuprate superconductors. To further expand our understanding of the chemical and magnetic properties of the Sr₂Cr_3-xMn_xAs₂O₂ solid solution, Sr₂Cr₂MnAs₂O₂ has been synthesized. The compound crystallizes in the I4/mmm tetragonal space group with a refined stoichiometry of Sr₂Cr_1.85Mn_1.15As₂O₂. The M(2) site within the M₂Pn₂ slab is occupied by 42.7% Cr and 57.3% Mn, and the magn
