Fig. 2: Electron diffraction on the Sr₂RuO₄ crystal.

a Indexed electron diffraction pattern (white dots) in the (q_∣∣, q_⊥) plane, including the reduced Brillouin zone (green) for equal layers along the c-axis. b Brown momentum range [see (a)] in which loss spectra are recorded for various q_∣∣ and q_⊥ values. The colors purple, blue, green, yellow, and red correspond to q_⊥ equal 0, 0.1, 0.2 0.3, and 0.4 Å⁻¹, respectively. The diameter of the filter entrance aperture [indicated by the colored circles in (b)] defining the momentum range in one EEL spectrum (momentum resolution) corresponds to a momentum of 0.04 Å⁻¹.
