The full 2D diffraction pattern of Fe + MgO collected at ∼280 (5) GPa [MgO EoS (Jacobsen et al., 2008)] or 313 (5) [MgO EoS (Zha et al., 2000)] collected from the t-DAC. The sample chamber was surrounded by an Fe0.79Si0.07B0.14 metallic glass gasket. We observe a strong, clear signal with a negligible contribution from the gasket material. As indicated, the strongest powder-like signal belongs to h.c.p.-Fe and MgO. There is an additional contribution from diamond anvils in the form of strong spots. Data were collected at a wavelength of 0.4834 Å. |
