Abstract

Spin diffusion and spinlattice relaxation in solids containing paramagnetic impurities under influence of a multiple-pulse spin-locking radio-frequency sequence are studied theoretically and experimentally. The diffusion equation obtained provides a clue for determination of the time dependent magnetization. The spinlattice relaxation time is calculated as a function of the correlation time and multiple-pulse field parameters. From the experimental data the spin diffusion coefficient, the radius of the spin diffusion barrier, and the correlation time for very slow molecular motion in polycrystalline (C ₂F)_n system are estimated and found to be D∼7.1×10^-12cm²/s, r_c∼4. 8×10^-10m, and τ^c∼10.2μs, respectively.
