Garbarino We report on high-pressure powder synchrotron x-ray diffraction studies on MFe_{2} As_{2} (M=Ba, Ca) over a range of temperatures and pressures up to about 56 GPa using a membrane diamond-anvil cell. Our data indicate a phase transition to a collapsed tetragonal phase in both compounds upon compress... [Phys. Rev. B 83, 054503] Published Wed Feb 09, 2011
