From: Phase diagram of YbZnGaO4 in applied magnetic field

Fig. 5

a Intensity plot of Hc/Hs in Jz±−J±± axes for Δ = 1.1, J2 = 0.05J. Hc is the critical field of the transition from the four- to three-sublattice state, Hs is the saturation field. Dot represents parameter set used in SpinW calculations. H was scanned in steps of 0.1 and units of gμBJ, equivalent to steps of 0.021 in terms of Hc/Hs for Hs = 4.815. b Same as in a for Δ = 0.8, where step size in Hc/Hs was 0.026 corresponding to Hs = 3.87. c Intensity plot of the magnetic susceptibility, χ = dM/dH, in the Jz±−H plane for Δ = 1.1, J2 = 0.05J, and J±± = 0. Singularities correspond to phase transitions. d Same as in c for Δ = 0.8.
