Pressure-Induced Irreversible Disorder in $β^{\prime}$-Mn$_3$(PO$_4$)$_2$: A High-Pressure X-ray Diffraction and Density-Functional Theory Study

The high-pressure structural behavior of $β^\prime$-Mn$_3$(PO$_4$)$_2$ was investigated using synchrotron X-ray diffraction up to 20 GPa combined with density-functional theory calculations.

The high-pressure structural behavior of $β^\prime$-Mn$_3$(PO$_4$)$_2$ was investigated using synchrotron X-ray diffraction up to 20 GPa combined with density-functional theory calculations. At ambient conditions, $β^\prime$-Mn$_3$(PO$_4$)$_2$ crystallizes in a monoclinic…
