Evidence for Two Superconducting Gaps in
X. K. Chen, M. J. Konstantinovic, J. C. Irwin +2
We have measured the Raman spectra of polycrystalline MgB from 25 {\cm} to 1200 {\cm}. When the temperature was decreased below the superconducting transition temperature $T_…
Doping Dependence of the Pseudogap in La(2-x)Sr(x)CuO(4)
J. G. Naeini, X. K. Chen, J. C. Irwin +3
We report the results of Raman scattering experiments on single crystals of La(2-x)Sr(x)CuO(4) that span the range from underdoped (x = 0.10) to overdoped (x =0.22). The spectra ar…
Evidence for Magnetic Pseudoscaling in Overdoped La(2-x)Sr(x)CuO(4)
J. G. Naeini, X. K. Chen, K. C. Hewitt +5
We report the results of electronic Raman scattering experiments on an overdoped La(1.78)Sr(0.22)CuO(4) single crystal as a function of temperature. The scattering rate Gamma(w->0,…
Comment on "Superconducting gap anisotropy vs. doping level in high-T_c cuprates" by C. Kendziora et al, PRL 77, 727 (1996)
K. Hewitt, T. Devereaux, X. K. Chen +3
In a recent paper Kendziora et al concluded that the superconducting gap in overdoped Bi-2212 is isotropic. From data obtained from electronic Raman scattering measurements, their…
