a Schematic picture of the experimental geometry with the strain device. b Sketch of the crystal and magnetic structure of an IrO2 plane. Black (gray) circles represent Ir (O) atoms. Black arrows represent pseudospins. c Orthorhombic deformations of xy type (left, strain along the [1 0 0] direction) and x2 − y2 type (right, strain along the [1 1 0] direction). Solid (dashed) lines represent the strained (undistorted) lattice. Orange arrows show the applied stress directions. d Raman spectra of B2g symmetry measured below and above TN. The left panel shows the low-energy range, where a single-magnon peak is observed below TN.
