Vd. Natsik et al., RELAXATION DRAG OF DISLOCATIONS IN C60 CRYSTALS AT LOW-TEMPERATURES, Physica status solidi. a, Applied research, 157(2), 1996, pp. 303-309
Dynamic interaction of dislocations with the rotational degrees of fre
edom of C-60 molecules has been analysed. The results indicate that th
e main features of the temperature dependence of the microhardness in
the f.c.c. --> s.c. phase transformation region and at temperatures of
the orientational glass transition at 160 K and below can be explaine
d by the contribution of this interaction to dislocation drag during d
eformation.
