Abstract

The magnetic flux pinning properties of high-Tc grain boundary junctions in low magnetic fields are studied here numerically. The grain boundary junctions are modelled as inductive, one-dimensional arrays of narrow Josephson junctions, consisting of both conventional (0)-junctions and unconventional (π)-junctions. Attention is paid especially to the influence of (π)-junctions on flux pinning in the array. The results show that the presence of unconventional (π)-junctions among conventional Josephson junctions may significantly improve magnetic flux pinning in arrays where the parameter β = 2πLIJ0 is low (β<π).
