<font size="4"><b>Second harmonics and anomalous Josephson effect in
superconducting multilayers</b></font> <br>
<br>
<div class="abstract tex">
In our work [1] we investigate the current-phase relation in a
planar diffuse tunnelling SIS′IS-junction in which the S′-layer
contains in addition a strong spin-orbit interaction and a Zeeman
term. The possibility of calculating the current-phase relation
depending on the phase jump of the order parameter at each
boundary by perturbation theory methods allows us to find the
current dependence on the applied magnetic field. Since taking
into account the spin-orbit and Zeeman terms leads effectively to
the appearance of an additional contribution to the vector
potential, each harmonic of the current-phase relation is shifted,
which as a consequence leads to the anomalous Josephson effect in
this system.
