X-ray and Raman measurements have been performed on samples of polymerized fullerenes, which show weak ferromagnetism. For pressure-polymerized fullerenes, ferromagnetic features are observed in a narrow temperature range very close to the limit of stability of the cages. Raman spectra show that the type of polymerization is probably of less importance. Strong structural inhomogeneity of the samples suggests that the magnetic phase forms a minority phase in a non-magnetic matrix.
