Figure 5
X-ray emission spectra of Fe Kβ collected from a single crystal of magnesiowüstite-(Mg0.75,Fe0.25)O in the 〈110〉 orientation in a laser-heated DAC. The sample remains in the high-spin state at 47 GPa and 1300 K as the pronounced peak is still observed. Lines through the data points are guides to the eyes. The error on the energy resolution is less than 1 eV whereas the error on the intensity is approximately 5% of the intensity. |
