摘要：

Equilibrium and metastable states in nanometer-scale superconducting network systems are studied based on Ginzburg-Landau free energy and the phase transition in a magnetic field is investigated. It is discussed that superconducting fluctuation is affected significantly by the applied field and the strength of the fluctuation varies with respect to the field.
