50 Hz current-dependent losses of Bi2Sr2Ca1Cu2O(8+x)/Ag wires

50-Hz current-dependent loss measurements were carried out at 4.2 K on short straight samples of Bi2Sr2Ca1Cu2O(8+x)/Ag wires having high critical current densities of up to 15 kA/sq cm at 26 T. The ac power losses vary with to the square of the transport current, which is not consistent with the sim...

description 50-Hz current-dependent loss measurements were carried out at 4.2 K on short straight samples of Bi2Sr2Ca1Cu2O(8+x)/Ag wires having high critical current densities of up to 15 kA/sq cm at 26 T. The ac power losses vary with to the square of the transport current, which is not consistent with the simple Bean model. On the other hand, the losses depend linearly on the frequency of the alternating current, which would be compatible with hysteresis as the dominant loss mechanism. Loss values are found to be rather high and are not strongly influenced by bias magnetic fields up to 1 T. Several effects may contribute to the loss enhancement and its current dependence; however, the reason for this behavior remains to be clarified. (Author)
