(a) Sketch of visible-light diffraction from micrometric structures through a transparent crystal and (b–d) 3D superlattice probed at T=TC−2 K along the principal symmetry direction of the crystal, respectively, with the incident wavevector k parallel to (b) the z direction, (c) y direction and (d) x direction. Crystallographic analysis reveals the elementary cubic structure of lattice constant Λ shown in e. Scale bar, 1.2 cm.
