摘要：
The structural and electronic properties of BaCr2As2, which is isostructural to the 122 iron arsenide superconductors, are studied at high pressures using synchrotron x-ray powder diffraction, electrical resistivity measurements, and first-principles calculations. At a pressure of about 18.5 GPa, an isostructural phase transition to a collapsed tetragonal phase is observed, similar to that in BaFe2As2. In both phases, BaCr2As2 is a normal metal. Electronic structure calculations suggest a metallic and antiferromagnetic ground state with G-type magnetic order for the collapsed tetragonal phase.
