title: The absence of charge-density-wave sliding in epitaxial charge-ordered Pr(0.48)Ca(0.52)MnO(3) films.
abstract: For an epitaxial Pr(0.48)Ca(0.52)MnO(3) film on NdGaO(3), we use transmission electron microscopy to observe a 'charge-ordered' superlattice along the in-plane direction a. The same film shows no electrical signatures of charge order. The in-plane electrical anisotropy ρ(a)/ρ(c) = 28 is constant, and there is no evidence of sliding charge density waves up to the large field of ∼10(3) V cm(-1).
