Crystal Fields in PrX3 (X=In, Tl, Pb, Sn) Intermetallic Compounds with Cu3Au StructureWe have determined the crystal field splittings of Pr. in PrIn., PrTl., PrPb., and PrSn. by inelastic neutron scattering. The values of the deduced crystal field parameters are found to depend strongly on the constituent X, though all systems have nonmagnetic ground-states. The line widths in the different systems are compared.

ESR of Impurity as a Probe for the Host Exchange Interaction in Tm Van-Vleck CompoundsThe relaxation rate of an impurity in Tm Van-Vleck compounds with cubic structure is given for two limiting cases. Analysis of the ESR linewidth of Gd in TmP, TmSb and TmBi in terms of this theory yields information concerning the nature of the host fluctuation spectra and the host exchange parameters.

Reconciling Localized Moments with Lattice Periodicitylectrons. The problem of beginning with a very basic Hamiltonian, and recasting it to show localized moments and conduction properties is considered using degenerate perturbation theory. The result is a spin-Hamiltonian of typical form for the localized moments, with conduction electrons as well. At

Spin Waves in Anisotropic Magnetss planar single ion anisotropy, that the conventional spinwave theory is treating the single ion anisotropy very poorly. A new Bose operator expansion of tensor operators which is different from the Holstein Primakoff transformation will be discussed. The spin waves fulfil the Goldstone theorem exac

Spin Waves in HoZna have been analysed following a Green’s functions formalism to obtain the Fourier transform of interactions. The dispersion curves are well reproduced, but their precise energy position requires the addition of second order terms in the starting Hamiltonian.

Ground- and Excited-State Spin Waves in Holmium Phosphidebranches have been found which are almost independent of wave vector. The results are analysed in terms of a single-ion Hamiltonian containing a crystal-field and the effects of bilinear and quadrupolar pair interactions. At U.2 K excitedstate spin waves have been observed which correspond to transi

Neutron Crystal-Field Spectroscopy in PrSn3ns yields the crystal-field parameters x=0.79±0.03 and W=0.157±0.005 meV, which correspond to a Γ. ground state with an overall splitting of 74 K, and the paramagnetic molecular field parameter λ.=(1.8±0.3)×10.

Neutron Spectroscopy of the Crystal Field Splitting in Cerium Hydrided samples CeD. with concentrations between x = 1.94 and x = 2.75. For all samples investigated three crystal field transitions are observed which cannot be explained without taking into account a non-cubic surrounding of part of the Ce ions.
