Abstract

Dispersive behavior associated with the sharp periodic absorption lines that have been attributed to fluxon nucleation within Josephson junctions has been observed in single crystals of YBa₂Cu₃O_7-δ. Both the absorption and dispersion signals are interpreted with an rf SQUID model that associates the absorption signal with hysteresis and the dispersive signal with constant flux. The observed broadening above a threshold in microwave power of the absorption and dispersion into bands is given a particularly simple interpretation with the rf SQUID model. The observed constancy of the absorption amplitude with increasing rf power may also be interpreted simply on the basis of hysteresis.
