Notes. The samples 2, 5, and 11 are natural and 8, 10, and 12 are commercial products. Samples 1, 3, 4, 6, 7, and 9 are instead synthesised in the laboratories at the Astrophysikalisches Institut, Universitats-Stenwarte (AIU), and Osaka University. We adopted the metallic iron presented by Kortright & Kim (2000) and Lee (2010), with a shift in energy according to the work of Fink et al. (1985).
