Low temperature magnetic structure of geometrically frustrated SrHo2O4
Olga Young, Laurent C. Chapon, Oleg A. Petrenko
SrHo2O4 is a geometrically frustrated compound because the Ho^3+ ions are arranged in a network of triangles and hexagons and coupled with antiferromagnetic exchange interactions.…
Order-by-Disorder in the XY Pyrochlore Antiferromagnet Revisited
Pawel Stasiak, Paul A. McClarty, Michel J. P. Gingras
We investigate the properties of the XY pyrochlore antiferromagnet with local <111> planar anisotropy. We find the ground states and show that the configurational ground state entr…
Density profile of water confined in cylindrical pores in MCM-41 silica
Alan K Soper
It is shown that traditional estimates of the pore diameter in the porous silica material MCM-41-S15 (of order 15Å) are too small to allow the amount of water that is absorbed by t…
Probing high-energy electronic excitations using inelastic neutron scattering
Young-June Kim, A. P. Sorini, C. Stock +3
High-energy, local multiplet excitations of the d-electrons are revealed in our inelastic neutron scattering measurements on the prototype magnetic insulator NiO. These become allo…
Effect of Fermi Surface Nesting on Resonant Spin Excitations in Ba1-xKxFe2As2
J. -P. Castellan, S. Rosenkranz, E. A. Goremychkin +13
We report inelastic neutron scattering measurements of the resonant spin excitations in Ba1-xKxFe2As2 over a broad range of electron band filling. The fall in the superconducting t…
Dynamic fields in the partial magnetization plateau of Ca3Co2O6
P. J. Baker, J. S. Lord, D. Prabhakaran
Fluctuation dynamics in magnetization plateaux are a relatively poorly explored area in frustrated magnetism. Here we use muon spin relaxation to determine the fluctuation timescal…
