Fe K-edge XAS (a) and some examples of XMCD (b) as a function of pressure between the ambient-pressure b.c.c. phase and the high-pressure h.c.p. phase. Continuous lines correspond to examples of data measured simultaneously. The small glitches in the XAS at 7158 and 7171 eV in the high-pressure data are artifacts owing to small defects of the polychromator crystal (Mathon et al., 2004). |
