dc.description.abstractIn 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. Transport critical current density, J(c)(trans), of the whiskers in low magnetic field (between 0 and 270 Oe) and in a wide temperature region (5-75 K) was investigated. It was obtained that initially J(c)(trans) increased with increasing the magnetic field but then started to decrease with further increase on the magnetic field at all temperature values. We have investigated this problem in terms of the Bulk pinning model, the Geometrical barrier model and the Bean-Livingston surface barrier model. We have noticed that all these models were not fitted well to our data. However, we have modified the Bean-Livingstone model by adding a new parameter. It was found that this modified formula fitted well to the data obtained in this work and can give successful explanations to the other results obtained by other groups.en_US
