| Abstract: | The real and imaginary (lossy) components of a.c. susceptibility of high-T c superconductor YBa1·5Ca0·5Cu3O7−δ were measured as a function of temperature for different a.c. fields and frequencies. From the lossy component of the a.c. susceptibility the transport critical current density and its temperature dependence have been computed on the basis of Kim’s critical state model. |
