ad, Coloured overlays represent the local polarization for m= 1 (a), m= 3 (b), m= 7 (c) and m= 9 (d). Turquoise atoms have positive polarization and red atoms have negative polarization, as indicated by the colour bars. For each row of lutetium atoms, the mean lutetium displacement is plotted, with the bar representing the 20%–80% spread of the root-mean-square displacement. The colour of the bar indicates the direction of polarization.
