High temperature-treated compounds of mixed powders of cerium metal and C60 solid show fairly strong diamagnetic signal in the zero-field-cooling process and distinct ferromagnetic behavior in the field-cooling path below 13.5K and 15K, respectively. In the resistivity measurement of a compacted and long-term heated pellet of the powder a distinct drop of the resistivity with decreasing temperature is recognized around 20K, which is followed by a steep rise of the resistivity below 14K. These findings indicate an existing competition of superconductivity and ferromagnetism in this compound.
