โœฆ Synopsis

We report a systematic study of the temperature dependences of microwave absorption and low field dc magnetization in powder samples of the superconductor YIBa2Cu306.9. Both measurements indicate a transition temperature near 90 K. The temperature dependence of the diamagnetic susceptibility, as well as its value at TGZ T, are close to that of a conventional BCS supercondutor.

A systematic study of the relationship between particle dimensions and microwave absorption in micron size powders of superconducting Y~Ba2Cu307 reveals that small particles have negligible absorption at T< 0.8 To, and that the transition gets sharper as the grains get bigger. However, when the part
