Fig. 2

a Schematic diagram of the RUS experimental setup. The sample is mounted between two LiNbO3 transducers with the bottom one serving as ultrasonic driving source and the top one as pick-up. The magnetic field H is applied along [001], and the driving current I is along [100]. b Magnetic phase diagram established via RUS. The open circles are from \(\chi ^{\prime} (H)\), defined as the mid-point of spin polarization. The abbreviations denoting the different phases are: HM helimagnetic, CO conical, SKX skyrmion lattice, FD fluctuation disordered, PM paramagnetic, and PPM polarized paramagnetic.
