Özet

In this study, BiSrCaCuO superconducting whiskers were fabricated by using a glass-ceramics process. The T (c) value of the whiskers fabricated was found to be 90.2 K. I-V characteristics of the whiskers were studied in the temperature range of 10-70 K under low magnetic fields. The transport critical current density of whiskers was calculated between 19 and 0.63x10(4) A/cm(2) at 10-60 K. I-V data were fitted using the Levenberg-Marquardt technique. Results were discussed and so was their dependence on magnetic and electrical properties of the superconductors.
