Paper Title:
Magnetic, Thermal and Transport Properties of High-Pressure Synthesized Nanocrystalline EuC6
  Abstract

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.
