M. Turchinskaya et al., NONDESTRUCTIVE MAGNETOOPTICAL IMAGING ANALYSIS OF SUPERCONDUCTING (BI,PB)(2)SR2CA2CU3OX COMPOSITES, Journal of materials research, 11(7), 1996, pp. 1597-1600
The superconducting filaments in (Bi, Pb)(2)Sr2Ca2Cu3Ox/Ag composite t
apes have been imaged directly through the outer silver sheath of an u
npolished tape by means of a magneto-optical imaging technique. The im
ages reveal the morphology and alignment of the uppermost layer of fil
aments located as much as 112 mu m below the unpolished tape surface,
the depths of these filaments, and the homogeneity of the magnetic flu
x distribution within these filaments. These results demonstrate that
the magneto-optical technique is a valuable nondestructive tool for an
alyzing (Bi, Pb)(2)Sr2Ca2CU3Ox composite tapes.
