June 28, 2023

Two new innovative methods describe how to measure the electrical resistivity of liquid iron—such as that found in planetary cores—at extremely high pressures and temperatures. Prior to this, there were no experimental measurements of the electrical resistivity of liquid iron beyond 51 GPa and 2,900 K. These findings will help derive better theoretical models for the puzzling properties of liquid iron.
