Extended Data Fig. 5

Bulk magnetization data for La1.86Sr0.14CuO4 is from Nakano et al.36. 63Cu Knight shift data for YBa2Cu4O8 is from Curro et al.68. Unlike YBa2Cu3Oy, for which chain-oxygen atoms become mobile above room temperature, stoichiometric YBa2Cu4O8 does not suffer this problem. This allows one to see that the broad susceptibility maximum, inherited from the behaviour of the undoped square lattice, is present in the YBCO system as well.
