摘要：
Bi-2212 single crystal whiskers have been fabricated on the surface of the bulk glass BSCCO pieces prepared by the melt-quenching process. The characterizations of the whiskers were made using XRD, SEM-EDX, M-T, M-H analysis. Pinning force calculations were performed using magnetic hysteretic loops taken at different temperatures and results obtained were analyzed using scaling law equation. The whiskers fabricated showed higher pinning at low temperature. The pinning force at 10 K was calculated to be 3,83x10(11) N/m(3) under 2 T applied magnetic field. The results obtained showed that a decrease on the flux pinning force decreases the critical current density of whiskers.
