Data sets for "Pressure dependent structure of amorphous magnesium aluminosilicates: The effect of replacing magnesia by alumina at the enstatite composition"

Data sets used to prepare Figures 1 and 3-18 in the Journal of Chemical Physics article entitled "Pressure dependent structure of amorphous magnesium aluminosilicates: The effect of replacing magnesia by alumina at the enstatite composition." The data sets describe the effect on the structure of glassy (MgO)_{0.375}(Al_2O_3)_{0.125}(SiO_2)_{0.5} of increasing the pressure from ambient to 8.2 GPa. They also describe the effect on the structure of releasing the pressure from 8.2 GPa and recovering the glass to ambient conditions. The structure was measured using in situ high pressure neutron diffraction. The coordination environment of aluminium in the as-prepared and recovered material was also probed using solid state 27Al nuclear magnetic resonance spectroscopy.
