Abstract
We have measured he microwave dissipation at 10 GHz through the imaginary p art of the susceptibility, chi " in a Bi2Sr2CaCu2O8 single crystal in an ex ternal static magnetic field H parallel to the c-axis at various fixed temp eratures. The characteristics of chi " (H) exhibit a sharp step at a field H-step, strongly dependent on the amplitude of the microwave excitation h(a lphac). The characteristics of h(alphac) vs. H-step, reveal he behavior exp ected for the magnetic-field dependence of Josephson coupling.
