摘要: The transport properties ol Bi-based multifilamentar~ tapes on magnetic field have
been studied. The tapes lvere fabricated by po\rder-in-sil\.er tubing technique followed
by appropriate sintering. The hysteretic behavior of transport critical current of the
tapes Gth bending strain has been investigated. The experimental data are obtained
at 77 K under field cycling from 0 to 1000 G to 0. The critic4 current density under
a field does not vary xhen bending strain is smaller than a critical bending strain, and
then decreases gradually with increasing bending strain. The normalized values are
unafiected by bending strain up to 1.31%. The remnant magnetic filed H, associated
with the flux pinning force is obtained by an empirical expression! ivhich is similar to
generalized critical sLate model. The H, is aim-t a constan: for all bending strain.
This observation indicates that the intrinsic pinning properLies are not varied with
bending strain.
