Abstract
  • The transport and noise properties of Pr0.7Ca0.3MnO3 epitaxial thin films in the temperature range from room temperature to 160 K are reported. It is shown that both the broadband 1 / f noise properties and the dependence of resistance on electric field are consistent with the idea of a collective electrical transport, as in the classical model of sliding charge density waves. On the other hand, the observations cannot be reconciled with standard models of charge ordering and charge melting. Methodologically, it is proposed to consider noise-spectra analysis as a unique tool for the identification of the transport mechanism in such highly correlated systems. On the basis of the results, the electrical transport is envisaged as one of the most effective ways to understand the nature of the insulating charge-modulated ground states in manganites. (literal)
