Influence of exchange couplings. Magnetization region occupied by the chiral phase (red bars), as a function of exchange couplings [\(J_F = (J_2 + J_2^\prime )/2\), \(J_2 / J_2^\prime = 2\) fixed]. The magnetization M is normalized to the saturation magnetization \(M_\text {sat}\). The end regions of red bars are plotted less opaque to represent uncertainties as applicable. Transparent squares, centered at the corresponding values of \(J_F\) and \(J_\perp\), indicate the projections of the red bars onto the \(M=0\) plane. The zero-field phase boundaries towards the dimerized (light green) and commensurate phases (blue) of the frustrated ladder with \(J_2=J_2^\prime\)11, redrawn using data points provided by the authors of Ref. 11, are included for comparison.
