摘要：

C60 single crystals free from solvent contamination were grown from its vapor up to a size of 0.5 x 1.2 x 1.6-2 mm3 by a method of periodic oscillation of the crystal temperature. The heat capacity of the crystals exhibited a sharp peak at 260 K with hysteresis of less than 1.2 K. The XRD patterns from room-temperature to 50 K show a transition of structure from face-centered cubic to simple cubic at 260 K. Values of 14.5 +/- 0.6 and 17.5 +/- 0.5 for the Vickers hardness of C60 crystals on the (100) and (111) faces, respectively, indicated that C60 is a very soft material.
