Abstract

The authors report DC magnetization and AC susceptibility measurements on both micron-size powders and sintered samples of several high-temperature superconductors. The powder data confirm previous findings that the materials can be treated as conventional superconductors with s-wave pairing. The AC results on sintered slabs are interpreted using bean´s model and yield the temperature dependence of the shielding current
