Phase diagram and spin Hamiltonian of weakly-coupled anisotropic S=½ chains in CuCl2·2((CD3)2SO)
(American Physical Society, 2007-06-01)
Field-dependent specific heat and neutron scattering measurements were used to explore the antiferromagnetic S=½ chain compound CuCl2·2((CD3)2SO). At zero field the system acquires magnetic long-range order below TN=0.93 ...
S=½ chain in a staggered field: high-energy bound-spinon state and the effects of a discrete lattice
(American Physical Society, 2005-03-01)
We report an experimental and theoretical study of the antiferromagnetic S=½ chain subject to uniform and staggered fields. Using inelastic neutron scattering, we observe a bound-spinon state at high energies in the linear ...
Coupled Magnetic and Ferroelectric Domains in Multiferroic Ni3V2O8
(American Physical Society, 2009-08-21)
Electric control of multi-ferroic domains is demonstrated through polarized magnetic neutron diffraction. Cooling to the cycloidal multi-ferroic phase of Ni3V2O8 in an electric field E causes the incommensurate Bragg ...
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 ...
