Manifestation of Correlation Effects in the photoemission spectra of Ca $_{1 - x}$ Sr $_{x}$ RuO $_{3}$

M. Takizawa, D. Toyota, H. Wadati +8

We have measured soft x-ray photoemission and O 1{\it s} x-ray absorption spectra of Ca $_{1 - x}$ Sr $_{x}$ RuO $_{3}$ thin films prepared {\it in situ}. The coherent and incoherent parts ha…

Hysteresis and Anisotropic Magnetoresistance in Antiferromagnetic $N d_{2 - x} C e_{x} C u O_{4}$

X. H. Chen, C. H. Wang, G. Y. Wang +4

The out-of-plane resistivity ( $ρ_{c}$ ) and magnetoresistivity (MR) are studied in antiferromangetic (AF) $N d_{2 - x} C e_{x} C u O_{4}$ single crystals, which have three types of noncollinear…

Structural Phase Transitions and Sodium Ordering in Na0.5CoO2: a Combined Electron Diffraction and Raman Spectroscopy Study

H. X. Yang, C. J. Nie, Y. G. Shi +6

The nonstoichiometric NaxCoO2 system exhibits extraordinary physical properties that correlate with temperature and Na concentration in its layered lattice without evident long-ran…

Anisotropy and Field-Dependence of the Spin-Density-Wave Dynamics in the Quasi One-Dimensional Conductor (TMTSF)_2PF_6

P. Zornoza, K. Petukhov, M. Dressel +3

The anisotropic and non-linear transport properties of the quasi one-dimensional organic conductor (TMTSF)_2PF_6 have been studied by dc, radiofrequency, and microwave methods. Mic…

Dimensional crossover and anomalous magnetoresistivity in single crystals $N a_{x} C o O_{2}$

C. H. Wang, X. H. Chen, J. L. Luo +6

The in-plane ( $ρ_{ab}$ ) and c-axis ( $ρ_{c}$ ) resistivities, and the magnetoresistivity of single crystals $N a_{x} C o O_{2}$ with x = 0.7, 0.5 and 0.3 were studied systematically. $ρ_{ab}(T…

Quantum Versus Jahn-Teller Orbital Physics in YVO $_{3}$ and LaVO $_{3}$

Zhong Fang, Naoto Nagaosa

We argue that the large Jahn-Teller (JT) distortions in YVO $_{3}$ and LaVO $_{3}$ should suppress the quantum orbital fluctuation. The unusual magnetic properties can be well explained…
