Abstract
Annealing effects on the magnetic and structural properties of single-crystal TDAE-C60 are investigated. When a crystal is well-annealed at 350 K, ferromagnetic ordering takes place below 16 K, though no magnetic phase transition is shown in as-grown crystal. The saturated magnetization was obtained to be 0.9±0.1μB per C60. It was first found that the well-annealed crystal shows a structural phase transition around 180 K, probably associated with the orientational ordering of C60 molecules. On the other hand, the as-grown crystal undergoes no structural phase transition at least down to 30 K while the motion of C60 molecules is restricted below around 150 K. The possible relation between the low-temperature structure and the magnetic ordering is discussed.
