Phase boundary of the hexagonal-prism superconducting network in a magnetic field

In this paper, we systematically study the phase boundary T_c(\vecH) of a hexagonal-prism superconducting network in an external magnetic field \vecH of arbitrary magnitude and direction. The result indicates that the phase boundary of the hexagonal-prism superconducting circuit varies more sharply than that of the cubic circuit. The potential applications of the hexagonal-prism superconducting circuit are also discussed.
