The linear coefficients α(T) of N₂–C₆₀ solutions with 9.9% and 100% of the C₆₀ lattice interstitials filled with N₂ have been investigated in the interval 2.2–24 K. The dependence α(T) has a hysteresis suggesting co-existence of two types of orientational glasses in these solutions. The features of the glasses are compared. The characteristic times of phase transformations in the solutions and reorientation of C₆₀ molecules have been estimated.
