Title: Crystal electric field in RAgSb{sub 2} (R = Ho, Er, Tm) intermetallic compounds

Abstract

The magnetic scattering spectra of RAgSb{sub 2} (R = Ho, Er, Tm) intermetallic compounds are measured and their crystal electric field parameters are determined using inelastic neutron scattering. It is revealed that the ground state is a nonmagnetic singlet for the HoAgSb{sub 2} compound, a Kramers doublet with a strongly anisotropic g factor for the ErAgSb{sub 2} compound, and a quasi-doublet (random doublet) characterized by an extremely anisotropic g factor for the TmAgSb{sub 2} compound. The exchange interaction is estimated in the molecular field approximation. The magnetic properties of the RAgSb{sub 2} compounds are analyzed in terms of the energy level schemes and eigenfunctions determined in this study. The calculated anisotropic magnetic susceptibilities for all compounds are in good agreement with the experimental data obtained for single crystals.

  • Measurements of the magnetic susceptibility of the R/sub 2/In compounds from 4.2 to 270 K have been made. All compounds except Y/sub 2/In and Sm/sub 2/In exhibit Curie-Weiss behavior at high temperatures with effective magnetic moments agreeing reasonably well with the free-ion 3+ picture modified by RKKY exchange except for Gd/sub 2/In, which gives an unusually high value for the effective moment. With the exception of Y/sub 2/In all other members exhibit susceptibility maxima. Gd/sub 2/In, Tb/sub 2/In, and Dy/sub 2/In order antiferromagnetically. Gd/sub 2/In is a metamagnetic compound. For the three compounds Ho/sub 2/In, Er/sub 2/In, and Tm/sub 2/Inmore » there is no indication of their type of ordering at low temperatures. The isotherm at 4.2 K of Nd/sub 2/In shows a ferromagnetic or ferrimagnetic behavior.« less
  • The crystal structure of R/sub 2/Ni/sub 2/In compounds has been investigated by the single-crystal method using the example of Y/sub 2/Ni/sub 2/In. We selected single crystals in the form of an orthorhombic prism of an alloy of composition Y/sub 0.40/Ni/sub 0.40/In/sub 0.20/ prepared by electric-arc fusion of compacted yttrium (purity 0.9983 mass fraction Y), nickel (0.9992 mass fraction Ni), and indium (0.9999 mass fraction In) in purified argon under a pressure of 1.1 x 10/sup 5/ Pa and annealed at 870 K. Study of the single crystal was done by the Laue method, the rotation method, and the Weissenberg method,more » and subsequently also by taking the diffraction patterns on the Syntex P2/sub 1/ automatic diffractometer.« less
  • Crystals of nonstoichiometric phases Sr{sub 1-x}R{sub x}F{sub 2+x} (R are 14 rare-earth elements) and the ordered phase Sr{sub 4}Lu{sub 3}F{sub 17} with a trigonally distorted fluorite lattice were grown by the Bridgman method. Ten of 26 Sr{sub 1-} {sub x}R{sub x}F{sub 2+x} crystals, where R = La-Ho or Y, melt congruently. The isoconcentration series Sr{sub 0.90}R{sub 0.10}F{sub 2.10} includes four crystals with R = Er-Lu. The compositions corresponding to the maxima for the latter crystals were not determined. The concentration series, in which the mole fraction of RF{sub 3} varies from 10 to 50 mol %, were obtained for themore » crystals with R = La, Nd, and Gd. Most of the crystals are of good optical quality. To evaluate the composition changes in the course of crystal growth, the cubic unit-cell parameters were determined by X-ray powder diffraction. The line-broadening analysis revealed a nonmonotonic change of microdistortions as regards both the rare-earth content and rare-earth series. The changes in the lattice parameters and the congruent-melting points of the Sr{sub 1-x}R{sub x}F{sub 2+x} phases in the rare-earth series reflect the morphotropic transitions in the series of pure RF{sub 3} despite the fact that SrF{sub 2} dominates in nonstoichiometric fluorite crystals.« less
