Symbol:
Definition: phenomenon in which superconductivity is weakened or degraded at a grain boundary with a certain degree of structural and/or chemical disorder

Note 1 to entry: A grain boundary weak link is frequently observed for high temperature superconductors with short coherence length. Such a weak link is readily changed to a resistive state when excess magnetic field or current is applied.
