T–H phase diagram of β-Li2IrO3 with field along b-axis. a ΨI and ΨV obey a simple sum rule which suggests that spectral weight is exchanged between these parameters as a function of field. b Schematic representation of the moment direction in the zero field incommensurate (lower, green arrows) and the field induced zig-zag (upper, blue arrows) order projected on the Ir chains (gray) which propagate in the crystallographic a ± b directions (see also Fig. 1a). Note the propagation vector of the incommensurate order is not along the chain, but along the a-axis. c T − H phase diagram constructed by combining the normalized scattering intensity of a commensurate peak (gray scale contours), with the H* and T I extracted from magnetization and heat capacity measurements in Fig. 1 (blue diamonds), and a cusp observed in the field dependence of C p (red dots) (determination of the error bars is described in the caption of Supplementary Fig. 3). Note the parameter ΨV in principle grows as the structure factor and so ΨV ∝ \(\sqrt {{\rm{I}}_{\rm{V}}}\)
