Pressure-induced transition to the collapsed tetragonal phase in BaCr2As2

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...
