摘要：

We report muon-spin-rotation (muSR) measurements of the a-b magnetic penetration depth (lambda(ab)) in the vortex state of high quality single crystals of YBa2Cu3O6.95 Contrary to earlier muSR studies on powders and crystal mosaics, 1/lambda(ab)2 shows a strong linear temperature dependence below 50 K which weakens with increasing magnetic field. These results support recent microwave cavity measurements in zero field and provide further evidence for unconventional pairing of carriers.
