چکیده

Local antiferromagnetism coexists with superconductivity in the cuprates. Charge segregation provides a way to reconcile these properties. Direct evidence for modulated spin and charge densities has been found in neutron and X-ray scattering studies of Nd-doped La2−xSrxCuO4. Here we discuss the nature of the modulation, and present some new results for a Zn-doped sample. Some of the open questions concerning the connections between segregation and superconductivity are described.

Shadow bands, gap and pseudogaps in high-T c superconductors. Within the framework of the Charge Density Wave Quantum Critical Point (CDW-QCP) scenario for high-Tc super-conductors (HTCS), we introduce a model for tight-binding electrons coupled to quasi-critical fluctuations. In the normal state our model reproduces features of the Fermi Surface (FS) observed in ARP ES measurements on optimall...

An Electron Paramagnetic Resonance Study of Phase Segregation in Nd0.5Sr0.5MnO3

We present results of an electron paramagnetic resonance (EPR) study of Nd1−xSrxMnO3 with x = 0.5 across the paramagnetic to ferromagnetic, insulator to metal transition at 260 K (Tc) and the antiferromagnetic, charge ordering transition (TN = Tco) at 150 K. The results are compared with those on Nd0.45Sr0.55MnO3 which undergoes a transition to a homogeneous A-type antiferromagnetic phase at TN...

Electron Paramagnetic Resonance Study of Intrinsic Phase Segregation in CMR Manganite Nd0.5Sr0.5MnO3

We present electron paramagnetic resonance (EPR) results on Nd1−xSrxMnO3 with x = 0.5 which shows phase separation below the Curie temperature Tc= 250 K and compare with those of x = 0.55 which does not show any phase separation. EPR results clearly show the signature of phase separation in the former below Tc. From the analysis of temperature dependence of the resonant fields we conclude that ...

Optical response for a discrete stripe

The optical response of a charge stripe in the presence of pinning impurities is investigated. We address the issue of a discrete description of the stripe, and discuss its quantitative relevance with respect to a continuum one in the light of recent optical-conductivity measurements in cuprate compounds. The role of charge inhomogeneities in doped two-dimensional antiferromagnets has been rece...

Low-Temperature Structure and Magnetic Properties of the Spinel LiMn2O4: A Frustrated Antiferromagnet and Cathode Material

Powder neutron diffraction has been used to study the nature of the structural transition away from the Fd3m cubic structure upon cooling below ∼285 K in the spinel LiMn2O4. We report powder data taken between 10 K and 333 K and propose a large cell tetragonal structure in space group I41/amd for the material at 100 K. While complete segregation of the Mn3+ and Mn4+ ions is not possible in this...
