摘要：

Precise measurements of low-field magnetization and magnetic susceptibility of TDAE-C-60 (TDAE; tetrakis(dimethylamino)ethylene) by SQUID magnetometer are reported. Irreversible magnetization effect, i.e. a difference between zero-field-cooled and field-cooled magnetization is clearly observed for the first time. Also, an extremely slow relaxation of magnetization, characteristic of a spin-glass-like freezing process, is observed at low temperatures.
