Özet

In this study, 50 nm-18 mm in length superconducting single-crystal Bi-2212 whiskers have been fabricated using glass-ceramic BSCCO material. The microstructure, transport and magnetic properties were characterized by XRD, SEM-EDX, R-T, I-V and M-H analysis. Highly c-axis oriented single-crystal whiskers were produced without any grain boundaries in any crystallographic direction. T-c and T-zero were obtained to be 94.8 K and 92.8 K, respectively, and decreased with increasing the magnetic field. Magnetic properties, M-H curves of the whiskers, were investigated at 3 different constant temperatures up to 5 T. Symmetric hysteresis loops for all temperature and field cases were obtained and maximum J(c)(mag) value was calculated to be 4.58 x 10(6) Acm(-2) at 10 K for 0 T but dropped to 1.61 x 10(6) Acm(-2) at 30 K for 0 T.
