    Notes: Abstract We report measurements of the r.f. surface resistance of a wide variety of high-T c superconductors in bulk form and as films on silver substrates. Several apparatuses have been constructed and used for measurements at frequencies from 0.15 to 40 GHz and r.f. surface magnetic fields as high as 640 G. In every case in which the field dependence of the surface resistance was measured, the surface resistance increased monotonically with field amplitude through a transition region characterized by a strong field dependence. It then saturated at high field at a value of a few percent of the normal-state surface resistance just aboveT c . In the presence of this field dependence, the frequency dependence of the surface resistance changed from quadratic to less than linear.
