From cooperative paramagnetism to Neel order in Y2Ru2O7: neutron scattering measurements
(American Physical Society, 2008-01-01)
Spin correlations in the pyrochlore antiferromagnet Y2Ru2O7 with Curie-Weiss temperature ΘCW* - 1100 K and critical temperature TN = 77 K were examined through neutron scattering. For TN < T < ΘCW / 3 the data show spin ...
Bound spinons in an antiferromagnetic S=1/2 chain with a staggered field
(American Physical Society, 2004-07-02)
Inelastic neutron scattering was used to measure the magnetic field dependence of spin excitations in the antiferromagnetic S=1/2 chain CuCl2·2(dimethylsulfoxide) in the presence of uniform and staggered fields. Dispersive ...
Spin-trimer antiferromagnetism in La4Cu3MoO12
(American Physical Society, 2005-06-01)
La4Cu3MoO12 is a cluster antiferromagnet where copper spin-1/2 trimers form a network of strongly coupled spin trimers. The magnetic properties of this material have been examined using magnetic neutron scattering. At low ...
