Abstract

We have found a notorious hysteretic behavior in the dependence of the zero-resistance critical temperature obtained through resistivity (ρ) versus temperature (T) measurements with applied field (H e ) in High-T c granular superconductors. This behavior is explained semi-quantitatively based on the analogy between the present observation and a similar hysteresis found in the field dependence of the transport critical current in these materials.
