Observation of Enhanced Diamagnetism aboveTcin Indium Due to Thermodynamic Fluctuations

Abstract
We have observed a temperature-dependent enhanced diamagnetism above the critical temperature in pure bulk indium which we attribute to the effects of thermal fluctuations. The magnitude of the effect and the manner in which it scales with magnetic field are in agreement with a finite-field generalization of a zero-field result based on the Ginzburg-Landau theory.
