Abstract: Recent experiments on long hollow nanocylinders have reported an anomalous broadening and a multistep character of the resistive transition between normal and superconducting states with increasing magnetic field. Here we show that a first-order phase separation is not the reason for such behavior since it can arise only for a wall thickness that is much larger than in the investigated samples (similar to 30 nm). On the contrary, it is found that the destruction of global coherence in the transition neighborhood should be triggered by intrinsic long-range inhomogeneities of the cylinder.
