چکیده انگلیسی
The ac susceptibility, Ï=Ïâ²-jÏâ³, of a nearly square sample, cut from a coated conductor tape consisting of a high-temperature superconducting film and a covered copper stabilizer, is measured as a function of temperature, T, at several values of frequency, f. It is found that the Ï(f) at T>Tc can be well simulated by a modeling eddy-current susceptibility of the stabilizer, and there is an extra low-T stage, where Ï is not constant as expected and may be separated into two parts. The T-independent part is contributed by Meissner currents in the film with over-low |Ïâ²|, indicating that the film edge was damaged by cutting during tape and sample preparation. The T-dependent part is contributed by both eddy-currents and supercurrents, having a special f dependence with unknown mechanism. Both currents are interacted to each other in a complex way in the T range below and near Tc, resulting in interesting features in Ï(T,f).
