Abstract
Previously we have presented evidence for stripe order of holes and spins in with . Here we show, via neutron diffraction measurements of magnetic scattering, that similar order occurs in crystals with and . 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.
