Paper Title:
Fluctuating Diamagnetism in the Critical Region of the Superconducting Transition in Lead Nanoparticles
  Abstract

High resolution SQUID magnetization measurements in Lead nanoparticles are presented and discussed in terms of the fluctuation-related diamagnetism in the critical region of the transition to the superconducting state, where the first-order fluctuation theory breaks down. Exact expressions of the magnetization are derived from the Ginzburg-Landau functional in zerodimensional condition (i.e. for grain size lesser than the coherence length) and are used to achieve insights on the properties of the critical fluctuating diamagnetism.
