摘要：

Nuclear magnetic resonance studies of 19F in paramagnetic CeF3 show the ionic diffusion observed earlier in LaF3 and confirm the D43d (P3cl) crystal structure proposed by X-ray measurements. Between 245° K and 500°K, the ionic diffusion is due to the relatively rapid motion of fluorine ions in g sites, with EA = 0.13 eV, D0 = 1.7 × 10-9 cm2/sec and τc = 16μsec. © 1969.
