Abstract
The iron structural and magnetic transition between the magnetic (bcc-α) and the nonmagnetic (hcp-ε)phases has been studied monitoring the pressure dependence of the Fe-Kβ fluorescence line excited with monochromatic synchrotron radiation. The relative intensity of the two multiplets shows an S-shaped pressure curve with flex point at the known transition pressure of 130 kbar. The S width of ≈30kbar also coincides with the one determined in structural determinations, and in magnetism studies using Mössbauer techniques. This shows how the x-ray emission method can be used to probe the local magnetic properties of atoms under extreme thermodynamic conditionsKeywords
