Pressure dependence of ESR excitations in Cs2CuCl4 (T = 1.9 K, H||b). a Frequency-field diagrams of ESR excitations at different pressures. The data denoted in black are taken from ref. 6 (T = 1.5 K; 0 GPa). Dashed lines correspond to the fit results (see text for details). Source data are provided as a Source Data file. The inset shows a schematic picture of magnetic sites and exchange couplings in a triangular layer of Cs2CuCl4b ESR spectra (mode B) taken at 330 GHz at different pressures (the spectra are offset for clarity) (From Pressure-tuning the quantum spin Hamiltonian of the triangular lattice antiferromagnet Cs2CuCl4)
