ELECTRONIC SUPERCONDUCTOR PR2CUO4-XFX - MAGNETIC CORRELATIONS AT HIGH-TEMPERATURES (150-LESS-THAN-T-LESS-THAN-600 K) ACCORDING TO F-19 NMR DATA

The longitudinal and transverse relaxation rates of F-19 nuclei in Pr2 CuO4-xFx (x=0.20) samples are measured at high temperatures (150 K < T < 600 K). A feature is found in the temperature dependence of the rel axation rates at temperature T' congruent to 300 K. The magnetic prope rties of the electronic superconductor Pr2CuO4-xFx as a possible syste m with a stripe ordering of carriers and spins are discussed. (C) 1997 American Institute of Physics.
