Polarized neutron scattering studies of the kagome lattice antiferromagnet KFe3(OH)6(SO4)2
K. Matan, J. S. Helton, D. Grohol +4
We report polarized neutron scattering studies of spin-wave excitations and spin fluctuations in the S=5/2 kagome lattice antiferromagnet KFe3(OH)6(SO4)2 (jarosite). Inelastic pola…
Spin Correlations in the Geometrically Frustrated Pyrochlore Tb2Mo2O7
D. K. Singh, J. S. Helton, S. Chu +6
We report neutron scattering studies of the spin correlations of the geometrically frustrated pyrochlore Tb2Mo2O7 using single crystal samples. This material undergoes a spin-freez…
Spin Dynamics of the Spin-1/2 Kagome Lattice Antiferromagnet ZnCu_3(OH)_6Cl_2
J. S. Helton, K. Matan, M. P. Shores +9
We have performed thermodynamic and neutron scattering measurements on the S=1/2 kagome lattice antiferromagnet Zn Cu_3 (OH)_6 Cl_2. The susceptibility indicates a Curie-Weiss temp…
High-flux beam source for cold, slow atoms or molecules
S. E. Maxwell, N. Brahms, R. deCarvalho +7
We demonstrate and characterize a high-flux beam source for cold, slow atoms or molecules. The desired species is vaporized using laser ablation, then cooled by thermalization in a…
