Exploring Silicon’s Effect on Earth’s Core

Exploring Silicon’s Effect on Earth’s Core

High temperature (“hot”) [a] and quenched (“cold”) [b] integrated XRD patterns from burst heating run D1P2S3 (49-56 GPa), color-coded by temperature. Colored ticks below patterns identify reflections from hcp-Fe0.8Ni0.1Si0.1 (pink), fcc-Fe0.8Ni0.1Si0.1 (purple), and KCl (black). The sluggish fcc to hcp back-reaction can result in reflections from remnant fcc grains in patterns quenched from temperatures above the hcp-fcc transition.

Frustrated Antiferromagnet Jarosite Collapses under Pressure

Frustrated Antiferromagnet Jarosite Collapses under Pressure: Researchers using the U.S. Department of Energy’s Advanced Photon Source and National Synchrotron Light Source II investigating the pressure-temperature phase diagram of jarosite at pressures up to 121 GPa found that it’s antiferromagnetic magnetic order di
