Popis: |
Positive muon spin-rotation ($\ensuremath{\mu}\mathrm{SR}$) measurements on $\mathrm{Gd}{\mathrm{Ba}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{x} (x\ensuremath{\approx}7)$ 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 \AA{} (two samples) are extracted from the data. Two muon stopping sites exist for $T\ensuremath{\le}80$ K, one being associated with normal regions of the sample and the other with superconducting regions. |
