New Research Sheds Light on Iron’s Role in Earth’s Core Dynamics

Cutting-edge research using ultrafast X-ray absorption spectroscopy has revealed the structural and thermal behaviour of iron under extreme conditions mimicking Earth’s core. Findings show a hexagonal close-packed (hcp) structure at 240 GPa and 5,345 K, challenging prior theories favouring a body-centred cubic (bcc) form. The study provides critical insights into Ea...
