Figure 1
Illustration of the angular-dependent spectroscopic fingerprint of a pristine single-crystalline LCO particle. Panel (a) shows schematically the experimental configuration, where the particle is rotated along the vertical axis to facilitate the acquisition of the X-ray absorption spectra in different viewing angles [panels (c) to (f)]. Panel (b) shows the relative intensity profile of the horizontal and vertical polarization components as a function of the vertical elevation angle with respect to the X-ray source point that is ∼30 m upstream of the sample. The scale bar in panel (a) is 5 µm. |
