  The regular structure of superconducting nanoislands of alloy W-Ga-C was
fabricated on nanothin graphite using focused ion beam. The resistance vs
temperature dependence down to 1.7K and the magnetoresistance in field up to
24T were measured both for the bridge containing nanoislands and for the
reference bridge without islands. The difference between those measurements
demonstrates the proximity effect on a regular structure of superconducting
W-Ga-C nanoislands on nanothin graphite layer.
