Abstract
The magnitude of the powder spin susceptibility of an optimally doped superconductor (Hg1201) in the normal state is found to be nearly the same as that of near the optimally doped level. The Stoner enhancement factor of Hg1201 is larger than that of . The magnitude correlation of the Stoner enhancement factor is inconsistent with the effect of the recent theoretical Coulomb repulsion between electrons and that of the superexchange interaction of a charge transfer type.
