We present that electrons in the pyrochlore iridates experience a large interaction energy in addition to a strong spin–orbit interaction. Both features make the iridates promising for realizing novel states such as the topological Mott insulator. The pyrochlore iridate Eu₂Ir₂O₇ shows a metal–insulator transition at T_N ~ 120 K below which a magnetically ordered state develops. Using torque magnetometry, we uncover an unusual magnetic response. A magnetic field H applied in its a–b plane produces a nonlinear magnetization M_⊥ orthogonal to the plane. M_⊥ displays a d-wave field-angle pattern consistent with octupolar order, with a handedness dictated by field cooling, leading to symmetry breaking of the chirality ω. Lastlyl, a surprise is that the lobe orientation of the d-wave pattern is sensitive to the direction of the field when the sample is field-cooled below T_N, suggestive of an additional order parameter η already present at 300 K.
