Abstract

We have measured the microwave dissipation at 10 GHz through the imaginary part of the susceptibility, $\chi^"$ , in a BSCCO 2212 single crystal in an external static magnetic field $H$ parallel to the c-axis at various fixed temperatures. The characteristics of $\chi^"(H)$ exhibit a sharp step at a field $H_{step}$ which strongly depends on the amplitude of the microwave excitation $h_{ac}$ . The characteristics of $h_{ac}$ vs. $H_{step}$ , qualitatively reveal the behavior expected for the magnetic field dependence of Josephson coupling.
