Chromium and its common alloy CrV were recently shown to lie very close to a quantum critical point, exhibiting a range of behaviors including strongly temperature dependent Hall effect and a ‘pseudo-gap’, making it one of the simplest model systems in which to study such complex behavior. In this talk, we will discuss recent progress made toward understanding the interplay between the microscopic configuration of domains and domain walls and macroscopic behavior in Cr, including quantum critical behavior. The various hard x-ray techniques used in these studies include microscopy, x-ray photon correlation spectroscopy (XPCS) and high pressure diamond anvil cells that enable the direct imaging of the incommensurate antiferromagnetic domains and their dynamics.
