Abstract
We summarise our UxY1-xPd3 inelastic neutron scattering experiments and pre sent new neutron diffraction results for a single crystal of U0.45Y0.55Pd3. Long-range antiferromagnetic order is unambiguously observed below T-N = 2 2.5 K. in contrast, no long-range order is found in polycrystalline samples of U0.37Y0.63Pd3, U0.28Y0.72Pd3 and U0.2Th0.25Y0.55Pd3 but peaks in the ma gnetic susceptibility indicate spin-glass ordering in these compositions.
