ED phase diagrams. a The angle θ is measured from [111] towards the in-plane \([11\bar 2]\) direction. Phase diagrams in the Γ/K − h plane (FM Kitaev and AFM Γ) obtained using ED on the 24-site honeycomb cluster are shown for b θ = 5° and c θ = 90° at a fixed Γ′ = −0.03 in units of \(\sqrt {K^2 + {\mathrm{\Gamma }}^2} \equiv 1\). Circular and triangular markers represent peaks in the susceptibilities χΓ/K and χh, respectively. The intermediate-field KSL is adiabatically connected to the pure K limit at h = 0, as indicated by a black arrow inside the KSL. Colors represent the expectation value of the plaquette operator 〈Wp〉 in the ZZ and KSL, but not in the PS for clarity, which is discussed further in the main text. A sequence of phase transitions from ZZ order to the KSL, and finally the PS is found for θ = 5°, except near the pure K limit. The green line in b at Γ/K −0.37 denotes a representative slice where χh and S(q) are plotted in Fig. 2
