Abstract
Positive muon spin-rotation (μSR) measurements on GdBa2Cu3Ox (x≈7) have been conducted in the temperature interval 5.8-300 K. A temperature-dependent relaxation, attributable to Korringa relaxation of the Gd ion, as well as vortex-state relaxation are observed. Magnetic field penetration depths of approximately 1550 and 1900 Å (two samples) are extracted from the data. Two muon stopping sites exist for T≤80 K, one being associated with normal regions of the sample and the other with superconducting regions.
