Low temperature microhardness of Xe-intercalated fullerite C₆₀
The Vickers microhardness of Xe-intercalated polycrystalline fullerite C₆₀ (XexC₆₀, x ≃ 0.35)
 is measured in a moderately low temperature range of 77 to 300 K. A high increase in the microhardness
 of the material (by a factor of 2 to 3) as compared to that of pure C₆₀ single crysta...

| description | The Vickers microhardness of Xe-intercalated polycrystalline fullerite C₆₀ (XexC₆₀, x ≃ 0.35)
is measured in a moderately low temperature range of 77 to 300 K. A high increase in the microhardness
of the material (by a factor of 2 to 3) as compared to that of pure C₆₀ single crystals is observed.
It is shown that the step-like anomaly in the temperature dependences of the microhardness
of pure C₆₀ single crystals recorded under the orientational fcc-sc phase transition (Tc ≃ 260 K) is
also qualitatively retained for XexC₆₀, but its onset is shifted by 40 K towards lower temperatures
and the step becomes less distinct and more smeared. This behavior of ̅NV(T) correlates with x-ray
diffraction data, the analysis of which revealed a considerable influence of xenon interstitial atoms
on the peculiar features of fullerite thermal expansion due to orientational phase transitions (see
the paper by A.I. Prokhvatilov et al. in this issue).
