Abstract
The paramagnetic (mu(-)O) state formed at the oxygen site in high T-c LaSrCuO was used to probe an interaction between the localized moment of the paramagnetic electron and the conduction electrons via zero fie ld mu(-) spin relaxation. The enhanced relaxation rates consistently o bserved in the superconducting state of various Sr concentrations are explained as an effect of spin-pairing in the high T-c supercurrent.
