Abstract
Abstract
We argue that the Little-Parks effect, i.e., the oscillations of the superconducting critical temperature Tc
as a function of the magnetic flux threaded the superconducting cylinder, exhibits the feature of the fractional quantized flux when a ferromagnetic metal filled in the thin-walled superconducting shell, which caused by the exchange interaction. Our analysis is based on the transport-like proximity effect theory in the diffusive regime of Takahashi-Tachiki and shows explicitly that the extremum of Tc
in the vortex state L corresponds to the fractional values of fluxoid, and in particular the fractional flux quantum occurred at the L = 1 vortex state.
