Abstract :
A macroscopic quantity of the metallofullerene Gd@C82 has been isolated in pure form from various hollow fullerenes on pyrenylethyl silica with toluene as an eluent. Magnetization data for a powder sample of the isolated Gd@C82 have been obtained employing a SQUID magnetometer between +-5.5 T at temperatures ranging 3 to 200 K. These magnetization data, when scaled as a function of H/T, fall on a universal curve which is fitted to a Brillouin function consistent with J = 3.38 and g = 2. This is a signature of paramagnetic behavior.
