Fig. 4: Pressure evolution of SDW order.

a, Temperature dependencies of the internal field of the fast-precessing component measured at pressures of p = 0 GPa (ZP), 1.28 GPa and 2.31 GPa. b, Pressure dependencies of the magnetic ordering temperatures as determined in WTF μSR and ZF μSR experiments. The solid lines are linear fits with TN,WTF(p) = 148.3(1.5) + p × 2.8(4) and TN,ZF = 150.7(5) + p × 2.8(3). c, Pressure dependence of the internal field of the fast-precessing component. The solid and dashed lines are linear fits with Bint(0, p) = 143.7(3) – p × 0.44(22) and Bint(0, p) = 143.2(4), respectively. The error bars for individual data points correspond to one standard deviation from the χ2 fits.
