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.
