Abstract

Polycrystalline Ce₅Ge₄ compound (orthorhombic Sm₅Ge₄ -type structure, space group Pnma, No. 62) orders ferromagnetically at ~12 K (Tc). Low field dc magnetization and ac magnetic susceptibility data reveal presence of competing magnetic interactions below Tc. Heat capacity of Ce₅Ge₄ in zero applied field indicates a second order transition with a peak centered at 11 K. Powder neutron diffraction studies confirm the existence of a commensurate magnetic order in this compound at 10 K without a change of crystal structure. the Ce moments lie in the ab plane and the moment at Ce site is found to be only [formula omitted] at this temperature. © 2010, American Institute of Physics.
