First-order isostructural Mott transition in highly compressed MnO.

- C. Yoo, B. Maddox,
+9 authors W. Pickett - Physics, Materials SciencePhysical review letters
- 22 March 2005

We present evidence for an isostructural, first-order Mott transition in MnO at 105+/-5 GPa, based on high-resolution x-ray emission spectroscopy and angle-resolved x-ray diffraction data. The… Expand
