Phys. Rev. Lett. 78, 338–341 (1997)Coexistence of, and Competition between, Superconductivity and Charge-Stripe Order in La1.6-xNd0.4SrxCuO4Received 6 August 1996; published in the issue dated 13 January 1997 Previously we have presented evidence for stripe order of holes and spins in La1.6-xNd0.4SrxCuO4 with x = 0.12. Here we show, via neutron diffraction measurements of magnetic scattering, that similar order occurs in crystals with x = 0.15 and 0.20. Zero-field-cooled magnetization measurements show that all three compositions are also superconducting, with the superconducting transition temperature increasing as the low-temperature staggered magnetization decreases. These results directly demonstrate an intimate connection between stripe correlations and superconductivity. © 1997 The American Physical Society URL:
