Superconducting fullerite Rb[sub 3]C[sub 60] synthesized using alkali-metal azides as a source of the alkali metal shows time-dependent development of the superconducting phase based on electron spin resonance and low-field microwave absorption data. Time dependences of both signals observed for several hours after the synthesis are described by the Avrami diffusion model assuming the diffusion process Rb + C[sub 60] [yields] Rb[sub 3]C[sub 60]. The model permits calculation of the Josephson penetration depth as [lambda][sub J] [approximately] 1500 Angstroms, which is in agreement with other measurements. 18 refs., 2 figs.
