摘要：

Measurements of the complex AC susceptibility chi'-(j)chi" as a function of temperature and oscillatory magnetic field amplitude for a Y1Ba2Cu3O7 superconductor are reported. By observing the time-dependent analog signal produced in the AC susceptometer coils directly, the nonlinear magnetic response is demonstrated to arise from a nonsinusoidal waveform that is also phase-shifted from a purely inductive waveform. These observed waveforms are quantitatively interpreted within a weakly-connected loop model.
