Sliding charge-density waves in manganites

Access through your institution Buy or subscribe TO THE EDITOR: Cox _et al_.1 claim charge-density-wave (CDW) sliding in an untwinned epitaxial 80-nm-thick La0.5Ca0.5MnO3 film in which

superlattice transmission electron microscopy reflections confirm charge order. Their evidence consists of hysteresis in differential resistance, and broadband noise in the nonlinear

conductivity (NLC) regime. However, the measurements were performed using an irregular contact geometry that could support inhomogeneous heating currents, and there is no report of

narrow-band noise, which represents the most direct observation of sliding CDWs2. This is a preview of subscription content, access via your institution RELEVANT ARTICLES Open Access
