Abstract

The magnetic penetration depth in the vortex state of YBa2Cu3O6.95 has been measured as a function of temperature T and magnetic field H applied along the c-|Ax axis. The internal field distribution in single crystals was fit assuming a triangular vortex lattice with an average in-plane penetration depth λab=(λaλb)1/2=1155(3) Å, extrapolated to T=0 and H=0; λ(H,T) increases with both T and H. The large T-independent increase in λab with H is attributed to a strong nonlinear response as a result of the unconventional pairing in the superconducting state.
