Figure 8
Top panel: azimuthal dependence of the (201) Bragg reflection in URu2Si2. Solid (red) circles: σπ channel; black squares: σσ channel. The full (red) line is the theoretical intensity variation for magnetic dipoles ordered along [001]. The dashed red (dashed blue) line is the σπ (σσ) Ψ dependence of the intensity expected for xy quadrupole order. Bottom panel: experimental data compared with theoretical predictions for a dipole magnetic moment with an increasing component in the ab crystallographic plane.
