Two-magnon excitations observed by neutron scattering in the two-dimensional spin-5/2 Heisenberg antiferromagnet Rb2MnF4
T. Huberman, R. Coldea, R. A. Cowley +4
The low-temperature magnetic excitations of the two-dimensional spin-5/2 square-lattice Heisenberg antiferromagnet Rb2MnF4 have been probed using pulsed inelastic neutron scatterin…
Critical dynamics of a spin-5/2 2D isotropic antiferromagnet
R. J. Christianson, R. L. Leheny, R. J. Birgeneau +1
We report a neutron scattering study of the dynamic spin correlations in RbMnF, a two-dimensional spin-5/2 antiferromagnet. By tuning an external magnetic field to the valu…
X-ray Scattering and Magnetic Susceptibility Study of doped CuGeO_3
Y. J. Wang, Y. J. Kim, R. J. Christianson +6
We report comprehensive synchrotron x-ray scattering and magnetic susceptibility studies of the doped spin-Peierls materials Cu_{1-x}Zn_xGeO_3 and CuGe_{1-y}Si_yO_3. Temperature ve…
X-ray scattering study of two length scales in the critical fluctuations of CuGeO3
Y. J. Wang, Y. -J. Kim, R. J. Christianson +3
The critical fluctuations of CuGeO have been measured by synchrotron x-ray scattering, and two length scales are clearly observed. The ratio between the two length scales is fo…
Spin correlations in an isotropic spin-5/2 two-dimensional antiferromagnet
R. L. Leheny, R. J. Christianson, R. J. Birgeneau +1
We report a neutron scattering study of the spin correlations for the spin 5/2, two-dimensional antiferromagnet Rb_2MnF_4 in an external magnetic field. Choosing fields near the sy…
