a Schematic of the spin model. The circles with dots and crosses represent the direction of Dzyaloshinskii-Moriya vector and the plus and minus signs represent the signs of spin chirality when D < 0. b Magnetic field (h) dependence of scalar spin chirality χ1 for J1 = J2 = J2’ = − 1 and D = − 0.1. Each line is for T/|J1| = 0.1 (purple), 0.3 (blue), 0.5 (yellow), 0.7 (green), and 1.0 (red). The plots are for when the thermal average of transverse spin components is \(\langle {S}_{{ix}}^{2}+{S}_{{iy}}^{2}\rangle \le 0.1\).
