Magnetic correlations in the electron superconductor Pr2CuO4-xFx based on NMR data
Kukovitskii E. F. , Mustafin R. G., Teltel'baum G. B.
A reversible transition to an antiferromagnetically correlated state occurs in the normal phase of Pr2Cu04_^Fx. This transition increases the rate of nuclear spin relaxation by two orders of magnitude.
