(a) The Sr3Ir2O7 single crystal and ruby sphere loaded at the centre of the culet with a diameter of 250 µm. The sample has a triangular shape with edges of ∼65 µm parallel to the high-symmetry directions of the lattice. (b) The Sr3Ir2O7 and ruby sphere after the pre-indented laser-drilled gasket has been placed between the diamond anvils. A sketch of the experimental geometry is also shown. |
