Si et al Phase Diagram (IMAGE) Rice University Caption A simplified representation of a unified phase diagram depicting an ordered antiferromagnetic phase (gray) and a disordered paramagnetic phase (blue) that describe the correlated electronic behavior of heavy fermions and other known types of quantum materials. Researchers from Rice University, the Max Planck Institute for Chemical Physics of Solids and the Chinese Academy of Sciences used a combination of geometrical frustration, pressure and magnetic field to drive an alloy of cerium palladium and aluminum across a region (green) where physicists had previously only been able to speculate about the rules that govern electron behavior.
