摘要：

Angular dependent resistivity measurements of optimally doped YBa(2)Cu(3)O(7) films in fields H pulsed to 50 T are presented. Up to the highest H, the vortex melting field H(m) increases and vortex motion is reduced for H aligned with the correlated pinning centers along the main crystalline axes, otherwise 3D anisotropic scaling describes the vortex dynamics. For H parallel to ab, the rapid increase in H(m) at low temperatures and a critical exponent analysis near H(m) confirm the presence of the liquid-crystalline smectic phase predicted for layered superconductors.
