Coexistence of, and Competition between, Superconductivity and Charge-Stripe Order in La(1.6-x)Nd(0.4)Sr(x)CuO(4)

摘要

Previously we have presented evidence for stripe order of holes and spins inLa(1.6-x)Nd(0.4)Sr(x)CuO(4) with x=0.12. Here we show, via neutron diffractionmeasurements of magnetic scattering, that similar order occurs in crystals withx=0.15 and 0.20. Zero-field-cooled magnetization measurements show that all 3compositions are also superconducting, with the superconducting transitiontemperature increasing as the low-temperature staggered magnetizationdecreases.
