Argon effect on thermal expansion of fullerite C₆₀

Анотація:

The linear thermal expansion of compacted Ar-doped fullerite C₆₀(ArxC₆₀) is investigated at 2-12 K using dilatometric method. The thermal expansion of ArxC₆₀ was also studied after partial desaturation of argon from fullerite. It is revealed that argon doping resulted in the considerable change of the temperature dependence of the thermal expansion of fullerite. An explanation of the observed effects is proposed.
