Absence of the magnetization anomalies in magnetostriction measurements. Field dependence of a, relative deformation ∆L/L along the tetragonal axis, and b, its first derivative d(∆L/L)/dH, with ∆L ∥ H ∥ a-axis, at T = 0.4 K, for x = 0 (black), 0.02 (magenta), 0.03 (green), and 0.05 (blue). The arrows in a point to the onsets of deviation from linear fits to the low-field regions for each doping (dashed lines). The vertical dashed line marks the (pseudo-) 1/8 plateau, identified as the local minima in d(∆L/L)/dH vs. µ0H. Traces are shifted for clarity
