(a) Frequency-dependent ac-susceptibility \(\chi '\) measurement. (b) Temperature and field dependence of the \(\chi '\) signal around the \(A\)-phase. Dashed lines indicate the transition fields between the \(A\)-phase and neighboring conical phases. (c) Magnetic phase diagram constructed from the ac-susceptibility experiment.
