Abstract

The results of nonresonant microwave absorption (NRMA) studies in Bi2212 single crystals for the $H\Vert c$ axis and $H\Vert ab$ plane are reported. In the former orientation, over a few degrees below $T_c$ , the NRMA signal shapes evolve continuously as a function of temperature. We interpret these results as indicative of rapid strengthening of Josephson coupling between the pancake vortices in the $CuO_2$ bilayers on cooling below $T_c$ . For $H\Vert ab$ there is almost no change in the signal shape in the temperature range studied. In this case, no loss component attributable to Josephson coupling is observed.
