摘要：

We report that the field dependence of the magnetoabsorption (virgin curve) in all pristine granular CuO type (HTSC) superconductors follows a one-parameter expression. This "universal" result is combined with previous measurements on field and temperature dependences of microwave absorption in HTSC to demonstrate that a simple model based on resistively shunted Josephson junctions is adequate to qualitatively account for almost all the observations on powders, pellets, thin films and single crystals.
