摘要：

We report the temperature dependence of the magnetization hysteresis loops of high-quality YBa2Cu3O7 single crystals, each with a single unique orientation of twin boundaries. We have observed magnetization anisotropy in the temperature range 6-77 K for various magnetic fields applied normal to the c axis and parallel (stronger pinning) or perpendicular (weaker pinning) to the twin-boundary orientation, thus causing an anisotropic critical current density J(c). Magnetization-time-relaxation and Meissner-fraction measurements also support the above observation.
