Carrier density correlation with superconductivity—A universal law?
R Suryanarayanan M Rateau O Gorochov G Priftis H Pankowska L Ouhammou
Hall constants (
R H) at 300 K of three families of CuO-based superconductors are presented—the 123 YBaCuO with Fe substitution, the 2212 and 2223 Bi systems with Pb, Gd, Nd. Sm substitutions. In all these systems.R H is positive indicating hole conductivity.T c increases initially as the hole density (p =1/R He) increases and shows a maximum. Each family shows a maximum value ofT c but at different values ofp . These data along with the observation ofn -type conductivity in NdCeCuO are discussed in the light of certain models. -

We have studied the Mössbauer spectra of YBa2Cu3−
x Fex O7−d (11 compositions) and present here the results obtained from quantitative analyses of the paramagnetic and magnetic spectra.
