Bulk nanocrystalline EuC6 was prepared by the route of high pressure and high temperature synthesis. The material exhibits ferromagnetic behavior at low temperature. Its magnetic moment saturates at 2 K and 6 T to a value s ~0.64 B/f.u. The magnetic susceptbility obeys the Curie-Weiss law above ~60 K and the value of paramagnetic moment and Curie-Weiss temperature were found to be eff = 2.48 B and p = +12.5 K, respectively. Magnetic measurements show that europium atoms in the pressure synthesized EuC6 are not in a purely Eu+2 state but rather in a mixed-valence state.
