Abstract

Detailed measurements of the temperature and magnetic-field dependence of the magnetization and the magnetic relaxation of Nb films have been carried out. An irreversibility line, below which the remanent magnetization decayed logarithmically in time, was identified. The data were quantitatively compared to predictions of flux-creep, vortex-glass, and vortex-lattice-melting models. Only the melting model self-consistently explained the data.
