    Notes: Abstract Nuclear and magnetic structures of an annealed polycrystalline sample of the heavy-fermion compound CePd2Al3 prepared by arc-melting were investigated by neutron powder diffraction. The chemical structure corresponds well to the ordered hexagonal PrNi2Al3-type structure. The antiferromagnetic structure of CePd2Al3 with an ordered magnetic momentμ Ce=0.47(2)μ B at saturation is remarkably similar to that in the heavy fermion superconductor UPd2Al3. The additional incommensurate magnetic structures reported previously both for UPd2Al3 and CePd2Al3 are not observed in the present sample of CePd2Al3. At 1.4 K the magnetoresistivity of CePd2Al3 measured up to 14 T indicates only one field-induced phase transition at 3.0 T.

    Magnetic properties of CePd2Ga3 (1994)

    Notes: Abstract Field dependent specific heat measurements and a study of elastic neutron scattering experiments characterize CePd2Ga3 as a ferromagnetic Kondo compound with ordering in the basal plane belowT C ≈6 K. The crystal field ground state of cerium in this hexagonal compound is the |±1/2〉 eigenstate. In the scope of a phenomenological model, the coupling constant and the Kondo temperature have been deduced.
