Abstract We have performed detailed resistivity measurements as a function of temperature in the range from 12 to 300 K on oxygen loaded C60 films. We observe that two ordering phase transitions (i.e.,T 0=260 K andT g =90 K) are present in ϱ(T), which, in addition, strongly depends on the oxygen content. We find a decrease of both ordering temperatures with increasing oxygen concentrations. The mechanisms of oxygen diffusion are greatly enhanced in the ordered phase on heating. Finally, the transition to a glassy state atT g is detected as a point of reversibility of the resistivity curve as a function of temperature.
