Ki. Kugel et al., THE TWOFOLD EFFECT OF TWINS ON CRITICAL-CURRENT IN HIGH-T-C SUPERCONDUCTORS, Czechoslovak journal of Physics, 46, 1996, pp. 1025-1026
The pinning force and corresponding peaked contribution to the critica
l current are calculated for an array of parallel twins treated as pla
nar defects. The weak-link nature of twin boundaries is also taken int
o account. The features of the magnetization related to twins are disc
ussed.
