Sliding charge-density wave in manganites.
Stripe and chequerboard phases appear in many metal oxide compounds, and are thought to be linked to exotic behaviour such as high-temperature superconductivity and colossal magnetoresistance. It is therefore extremely important to understand the fundamental nature of such phases. The so-called stripe phase of the manganites has long been interpreted as the localization of charge at atomic site...
متن کاملNon-linear electrical response in a charge/orbital ordered Pr0.63Ca0.37MnO3 crystal: the charge density wave analogy.
Non-linear electrical response in a charge/orbital ordered Pr 0.63 Ca 0.37 MnO 3 crystal : the charge density wave analogy. Abstract Non-linear conduction in a charge-ordered manganese oxide Pr 0.63 Ca 0.37 MnO 3 is reported. To interpret such a feature, it is usually proposed that a breakdown of the charge or orbitally ordered state is induced by the current. The system behaves in such a way t...
متن کاملCharge-density-wave phase slip in NbSe3
We have studied the phase-slip process by which charge-density-wave (CDW) current is converted to single-particle current at electrical contacts. Transport and X-ray scattering measurements indicate that an excess voltage Vps dropped between current contacts induces a large static deformation of the CDW phase. The measured Vpsand temperature-dependent phase-slip rates are consistent with a mode...
متن کاملDynamical transition in sliding charge-density waves with quenched disorder.
We have studied numerically the dynamics of sliding charge-density waves ~CDW’s! in the presence of impurities in d51,2. The model considered exhibits a first-order dynamical transition at a critical driving force Fc between ‘‘rough’’ ~disorder dominated! (F,Fc) and ‘‘flat’’ (F.Fc) sliding phases where disorder is washed out by the external drive. The effective model for the sliding CDW’s in th...
