For both directions, $S/T$ decreases and becomes negative at low temperature, a signature that the Fermi surface undergoes a reconstruction due to broken translational symmetry. Above a clear threshold field, a strong new feature appears in $S_{\\rm b}$, for conduction along the $b$ axis only. We attribute this feature to ","authors_text":"B. Michon, D. A. Bonn, D. Graf, D.
