Abstract

We report a systematic study of a large peak in the microwave losses near T_c in micron-size powders of high-T_c superconducting cuprates. It is demonstrated that the effect arises because all the grains do not have a single T_c. The onset of superconductivity in some particles enhances the RF field "seen" by their neighbors leading to a net increase in absorption. The temperature regime of enhanced loss spans the extrema of the transition temperatures.
