Abstract
The tunneling interaction between two layers i and j leads to a finite coupling J between the condensate's orbital momenta li and lj. We compute the coupling between li and lj versus the external field applied to the sample. We obtain that an external field may influence J drastically, affecting its magnitude and even sign. If the sign of J is reversed, one may achieve an antiparallel orientation of li in the adjacent superconducting layers. It leads to the formation of intrinsic π-junctions inside the cuprate single crystals samples and is capable to explain the anomalous low-temperature bending-up of the ac conductivity observed in experiments.
