Quantization of magnetic flux at temperatures above the superconducting transition temperature

We investigated experimentally the quantization of the magnetic flux under conditions of fluctuation pairing. The conductivity oscillations of hollow thin-wall aluminum microcylinders were observed in a longitudinal magnetic field up to 8 °K. Qualitative agreement with theory is obtained under the assumption that the coherence length of the investigated samples is anomalously large.
