The research program of the Laboratory is concentrated on experimental investigations   of   novel   superconductors   such   as  high  temperature superconductors  and  organic  superconductors  and  on  the  studies  of artificial    rconducting    structures    such    as    Josephson    junctions, superconducting  multilayers  and  networks.  Large  part  of  the  present activity  is  related   to  the  study   of  the   vortex  dynamics   in   layered superconductors,   distributed   Josephson   junctions   and   one-and two-dimensional   Josephson   arrays  fabricated   in  the  Laboratory. The main   experimental   techniques   include   resistive,   thermoelectric, magnetic   and   magnetotransport   measurements   as  well  as  special precision   methods  such  as the   decoration   with  small  ferromagnetic particles, UID-magnetometer and SQUID-voltmeter. Device oriented work aims at realization of the superconducting flux-flow oscillator for sub-mm wave   receivers.  Josephson   pi-junction   based   on  superconductor- ferromagnet-superconductor (SFS) sandwiches are being studied now. It was  shown  that  the  crossover  from  the  0-state  to  the  pi-state of the junction    manifests    itself    as    anomalous    reentrant    temperature dependence  of  the  critical  current.  The crossover  to  the  pi-state also manifestes  itself  in  the  half-period  shift   of the external magnetic field dependence  of the transport  critical current  in the triangular SFS arrays.
