Temperature dependence of the critical current near Tc of superconductors containing twins
Bobrov V. S., Lebedkin M. A.
The change in the temperature dependence of the critical current near Tc during deformational twinning of niobium single crystals is evidence of the appearance of narrow superconducting channels in the twin region. Data which are evidence of a corresponding feature on the/c (T) curve in high-temperature superconductors are also discussed.
