Abstract

Precise measurements of low-field magnetization of TDAE-C60 (TDAE; tetrakis(dimethylamino)ethylene) by SQUID magnetometer revealed a clear “remanence” or “irreversibility”, i.e. difference in the temperature dependence between zero-field cooled (ZFC) and field cooled (FC) conditions below the freezing temperature Tf around 10 K. Also, an extremely slow relaxation phenomena of magnetization was observed. These “glassy” characteristics are reminiscent of a “spin-glass” with Tf at about 10 K as the nature of the magnetic ground state of TDAE-C60.
