N2 - A novel high magnetic field (8 T) spectrometer for muon spin rotation has been used to measure the temperature dependence of the in-plane magnetic penetration depth λab in YBa2Cu3O6.95. At low H and low T, λab exhibits the characteristic linear T dependence associated with the energy gap of a dx2 − y2-wave superconductor. However, at higher fields λab is essentially temperature independent at low T. We discuss possible interpretations of this surprising new feature in the low-energy excitation spectrum.
