Evolution of Magnetic and Superconducting Fluctuations with Doping of High- <i>T</i> <sub>c</sub> Superconductors
Evolution of Magnetic and Superconducting Fluctuations with Doping of High- <i>T</i> <sub>c</sub> Superconductors
Electronic Raman scattering from high- and low-energy excitations was studied as a function of temperature, extent of hole doping, and energy of the incident photons in Bi2Sr2CaCu2O8+/-delta superconductors. For underdoped superconductors, short-range antiferromagnetic (AF) correlations were found to persist with hole doping, and doped single holes were found to be …
