Argon effect on thermal expansion of fullerite C60 at helium temperatures

The linear thermal expansion of compacted Ar-doped fullerite C60 (Ar(x)C60) is investigated at 2 to 12 K using dilatometric methods. The thermal expansion of Ar(x)C60 was also studied after partial desaturation of argon from fullerite. It is revealed that argon doping resulted in the considerable ch...

Zusammenfassung:The linear thermal expansion of compacted Ar-doped fullerite C60 (Ar(x)C60) is investigated at 2 to 12 K using dilatometric methods. The thermal expansion of Ar(x)C60 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. (Author)
