Abstract

dc magnetic measurements on the high-temperature superconductor Tl2Ca2Ba2Cu3O10 (Tc=113 K), are reported. The zero-field-cooled and field-cooled magnetization curves coincide above a temperature Tirr which scales with the applied field as H13. The magnetization curves in the irreversible region scales; the scaling field is a simple function of geometrical factors and critical currents. The magnetization above Tc is not linear with the field, suggesting magnetic correlations in the CuO2 layers in the normal state.
