摘要：

We use a magnetic field to tune a highly anisotropic single crystal of oxygen-deficient YBa2Cu3O7-delta with a transition temperature of 2 K through the superconductor-insulator transition. The sheet resistance scales with temperature, 0.05 less-than-or-equal-to T less-than-or-equal-to 1.0 K, and field, 0 less-than-or-equal-to H less-than-or-equal-to 94 kOe, in a manner predicted by a theory for quantum phase transitions in disordered two-dimensional superconductors.
