摘要：

The reduction in flux motion resistivity due to pinning at twin boundaries in single crystal YBa2Cu3Ox is demonstrated. Pinning takes place only for magnetic fields aligned within a critical angle of the twin boundary plane. The critical angle varies with field direction and with field strength for H II c. The onset temperature of twin boundary pinning is established by its strong anisotropy, and shown to correspond with a feature in the temperature dependent resistivity for H II c.
