Nitrogen Contamination in Elastic Neutron Scattering

February 23, 2011
Author(s)
Song Xue Chi, Jeffrey W. Lynn, Ying Chen, William D. Ratcliff, Benjamin Ueland, Nicholas P. Butch, Shanta R. Saha, Kevin Kirshenbaum, Johnpierre Paglione
Nitrogen gas accidentally sealed in a sample container produces various spurious effects in elastic neutron scattering measurements. These effects are systematically investigated and the details of the spurious scattering are presented.

Cd-doping effects in Ce 2 MIn 8 (M=Rh and Ir) Heavy Fermion Compounds

June 15, 2010
Author(s)
C. Adriano, C. Giles, E. M. Bittar, L. N. Coelho, F. de Bergevin, C. Mazzoli, L. Paolasini, William Ratcliff, Richard Bindel, Jeffrey Lynn, Z. Fisk, P. G. Pagliuso
Low temperature magnetic properties of Cd-doped Ce 2MIn 8 (M = Rh and Ir) single crystals are investigated. Experiments of temperature dependent magnetic susceptibility, heat capacity and electrical resistivity measurements revealed that Cd-doping enhances

3:1 Magnetization Plateau and Suppression of Ferroelectric Polarization in an Ising Chain Multiferroic

January 26, 2009
Author(s)
Y.-J. Jo, Seoungsu Lee, E. Choi, H. Yi, William D. Ratcliff, Y. Choi, V. Kiryukhin, S.-W. Cheong, L. Balicas
Ferroelectric Ising chain magnet Ca3Co2−xMnxO6 (x≃0.96) was studied in magnetic fields of up to 33 T. Magnetization and neutron-scattering measurements reveal successive metamagnetic transitions from the zero-field ↑↑↓↓ spin configuration to the ↑↑↑↓ state

Electric field control of the magnetic state in Bi Fe O3 single crystals

May 12, 2008
Author(s)
Seoungsu Lee, William D. Ratcliff, S.-W. Cheong, V. Kiryukhin
Single crystals of multiferroic BiFeO 3 were investigated using neutron scattering. Application of an electric field reversibly switches ferroelastic domains, inducing changes in the magnetic structure which follows rotation of the structural domains. In
