摘要
The Cu NMR echo decay in rare earth co-doped lanthanum cuprate undergoes a crossover from Gaussian to exponential decay below T similar to 100K. This behavior indicates that the visible nuclei are coupled to others with much faster spin lattice relaxation rates. We interpret the NMR signal as arising solely from regions on the boundaries of large clusters of coupled electron spins.
