    Notes: We have performed a detailed study of the magnetization of Y0.6U0.4Pd3 (Tf∼10 K), which shows thermal, transport, and magnetic properties typical of a spin-glass system. Strong irreversibility is observed among our zero-field-cooled and field-cooled measurements in fields as large as 30 kOe. Thus, the freezing temperature displays an unusual weak dependence with field. We observe a very slow temporal dependence of the magnetization below the freezing temperature. The nonlinear susceptibility coefficients extracted from our data show an increase by a factor of approximately 20 when approaching the freezing temperature from above, but do not show a true divergence at Tf, and a scaling analysis does not seem to be possible. We compare these results with those expected for classical spin glasses, and propose a possible mechanism for the onset of frustration below x=0.45 in Y1−xUxPd3. © 1996 American Institute of Physics.

    Notes: While magnetic excitations in rare-earth systems in which the full ordered moment develops at each site have been comprehensively investigated, the excitations in sinusoidally modulated magnetic systems have proved to be rather elusive. Moreover, the character of the magnetic excitations in modulated magnets has been a subject of theoretical interest for many years. Neodymium metal exhibits a complicated sequence of modulated antiferromagnetic structures below TN =19.9 K. Following our first observations of magnetic excitations in this element, we have now carried out an extensive study of the spin dynamics of Nd, in both the modulated and paramagnetic phases. The wave vector and temperature dependence of several branches of excitations, whose energies range from 1 to 16 meV, have been measured and will be discussed in detail. Additionally, some results of the field dependence of the excitations will be presented.
