Manganese oxide (MnO) undergoes a Mott transition at 105 GPa, shifting from an insulating to a metallic state. This pressure-induced change involves a significant volume collapse and loss of magnetic properties.

Area of Science:

  • Condensed matter physics
  • Materials science
  • High-pressure physics

Background:

  • Mott transitions are crucial for understanding electronic properties of materials.
  • Manganese oxide (MnO) exhibits complex phase behavior under pressure.

Purpose of the Study:

  • To investigate the high-pressure phase transitions in MnO.
  • To identify the occurrence and nature of a Mott transition in MnO.

Main Methods:

  • High-resolution X-ray emission spectroscopy.
  • Angle-resolved X-ray diffraction.
  • High-pressure synthesis and characterization.

Main Results:

  • Observed isostructural, first-order Mott transition in MnO at 105±5 GPa.

  • Documented pressure-induced phase transitions: B1 (paramagnetic) to distorted B1 (antiferromagnetic) at 30 GPa, to B8 (paramagnetic) at 90 GPa, and to B8 (diamagnetic) at 105±5 GPa.
  • Confirmed Mott transition characterized by magnetic moment loss, ~6.6% volume collapse, and insulator-to-metal transition.

    • Conclusions:

    • MnO exhibits a pressure-induced Mott transition at 105 GPa.
    • The transition is marked by significant structural and electronic property changes.
    • High-pressure studies are vital for uncovering novel material behaviors.
