Magnetic properties of the superconducting ''superoxide'' La/sub 2/CuO/sub 4+/delta//

Journal Article · · Phys. Rev. B: Condens. Matter; (United States)
The magnetic properties of La/sub 2/CuO/sub 4+/delta// (/delta//le/0.13) have been determined by means of muon-spin rotation and relaxation in transverse and zero external fields. A fraction /ital f//sub SC/=0.6 of the sample was found to be superconducting with /ital T//sub /ital c//=35(1) K and extrapolated penetration depth /lambda/(0)=4200 A (powder average). The other phase, 40% of the sample volume, displayed static magnetic ordering identical to that of oxygenated La/sub 2/CuO/sub 4/. The /ital T/ dependence of /lambda/ is similar to that for samples of the La/sub 2/minus//ital x//Sr/sub /ital x//CuO/sub 4/ family.
