Figure 5
Bond distance variations from the average of the sum of the planar Δ2A + Δ2B distance deviations (blue squares), the apical one Δ1 (red circles), and half of the sum of the two planar distances minus the apical one (green stars) in zero field (left) and in a field of 480mT (same symbols and colors). Bond length values were obtained from Rietveld analysis assuming the tetragonal I4/mcm space group. The crossing of the dotted lines (same color code as the symbols) indicates the temperatures where the gradient of the linear regions changes. The dashed black vertical lines are a guide to the eye for the temperature where the mentioned anomalies occur.
