Abstract
The presence of a small concentration of in-plane Fe dopants in La1.87Sr0.13Cu0.99Fe0.01O4 is known to enhance stripelike spin and charge density wave (SDW and CDW) order and suppress the superconducting Tc. Here, we show that it also induces highly two-dimensional superconducting correlations that have been argued to be the signatures of a new form of superconducting order, the so-called pair density wave (PDW) order. In addition, using resonant soft x-ray scattering, we find that the two-dimensional superconducting fluctuation is strongly associated with the CDW stripe. In particular, the PDW signature first appears when the correlation length of the CDW stripe grows over eight times the lattice unit (∼8a). These results provide critical conditions for the formation of the PDW order.
