The absence of charge-density-wave sliding in epitaxial charge-ordered Pr0.48Ca0.52MnO3 films

For an epitaxial Pr0.48Ca0.52MnO3 film on NdGaO3, 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 Delta *ra/ Delta *rc = 28 is...

Description
Summary:For an epitaxial Pr0.48Ca0.52MnO3 film on NdGaO3, 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 Delta *ra/ Delta *rc = 28 is constant, and there is no evidence of sliding charge density waves up to the large field of ~ 103 V cm - 1.
