摘要:
Critical current densities and upper critical fields were measured for a single crystal of the highTcoxide superconductor, Bi2Sr2CaCu2O8+d, by transport within theabbasal plane and along thecaxis. The anisotropy in critical current densities was observed to beJc⊥/Jc∥=10, in agreement with the anisotropy in resistivity for the normal state. The scaling of the critical current density with the magnetic field was found. The critical current density scaled to zero at fieldsBc2in theabplane and along thecaxis which were in good agreement with the upper critical fields measured by transport.
