✦ Synopsis

We have studied the power-induced switching of a number of thin film YBa2Cu307 (YBCO) coplanar transmission line resonators at 8GHz. Switching occurs at current densities around 106 -107Acm -2 at low T, where it is hysteretic; at higher T it becomes non-hysteretic, and washes out in a narrow temperature range which we believe corresponds to the critical temperature Tcj of a single responsible weak link. We develop a thermal model which accounts for all of the observed features of the switching.

We have used non-resonant microwave absorption to study c-axis YBazCuaO7\_6/PrBa2Cu307\_ 6 superlanices and compare the response to a film of similarly grown YBa2Cu307\_~ (YBCO). Near the respective transition temperatures, the response of the supedattice samples and the YBCO film have similar ampli
