Momentum-Dependent Charge Transfer Excitations in Sr2CuO2Cl2 - Angle Resolved Electron Energy Loss Spectroscopy
Y. Y. Wang, F. C. Zhang, V. P. Dravid +4
Electron-hole pair excitations in the insulating cuprates were investigated by angle-resolved electron energy loss spectroscopy. The optically allowed and optically…
Resonant Two-Magnon Raman Scattering in Cuprate Antiferromagnetic Insulators
G. Blumberg, P. Abbamonte, M. V. Klein +3
We present results of low-temperature two-magnon resonance Raman excitation profile measurements for single layer Sr_2CuO_2Cl_2 and bilayer YBa_2Cu_3O_{6 + δ} antiferromagnets over…
Influence of oxygen ordering kinetics on Raman and optical response in YBa_2Cu_3O_{6.4}
A. A. Maksimov, D. A. Pronin, S. V. Zaitsev +7
Kinetics of the optical and Raman response in YBa_2Cu_3O_{6.4} were studied during room temperature annealing following heat treatment. The superconducting T_c, dc resistivity, and…
Antiferromagnetic Excitations and Van Hove Singularities in YBaCuO
G. Blumberg, Branko P. Stojkovic, M. V. Klein
We show that in quasi-two-dimensional -wave superconductors Van Hove singularities close to the Fermi surface lead to novel magnetic quasi-particle excitations. We calculate the…
Resonant two-magnon Raman scattering in antiferromagnetic insulators
Andrey V. Chubukov, David M. Frenkel
We propose a theory of two-magnon {\it resonant\/} Raman scattering from antiferromagnetic insulators, which contains information both on the magnetism and the carrier properties i…
