摘要：
The V-I characteristic curves of polycrystalline La1.8Sr0.2CuO4-delta show that the dissipation in the superconducting grain boundaries is quenched at high fields and temperatures. This new superconducting state is explained taking into account that the magnetization is the relevant parameter determining the quantum interference in the weak links. The only dissipation left in the sample after quenching that in the links is quantitatively understood within the vortex flow models.
