Magnons and continua in a magnetized and dimerized spin-1/2 chain
M. B. Stone, Y. Chen, D. H. Reich +4
We examine the magnetic field dependent excitations of the dimerized spin-1/2 chain, copper nitrate, with antiferromagnetic intra-dimer exchange meV and exchange alterna…
Phase diagram and spin Hamiltonian of weakly-coupled anisotropic S=1/2 chains in CuCl2*2((CD3)2SO)
Y. Chen, M. B. Stone, M. Kenzelmann +3
Field-dependent specific heat and neutron scattering measurements were used to explore the antiferromagnetic S=1/2 chain compound CuCl2 * 2((CD3)2SO). At zero field the system acqu…
Neutron scattering from a coordination polymer quantum paramagnet
Tao Hong, M. Kenzelmann, M. M. Turnbull +7
Inelastic neutron scattering measurements are reported for a powder sample of the spin-1/2 quantum paramagnet . Magnetic neutron scattering is identified a…
The S=1/2 chain in a staggered field: High-energy bound-spinon state and the effects of a discrete lattice
M. Kenzelmann, C. D. Batista, Y. Chen +4
We report an experimental and theoretical study of the antiferromagnetic S=1/2 chain subject to uniform and staggered fields. Using inelastic neutron scattering, we observe a novel…
Extended quantum critical phase in a magnetized spin-1/2 antiferromagnetic chain
M. B. Stone, D. H. Reich, C. Broholm +4
Measurements are reported of the magnetic field dependence of excitations in the quantum critical state of the spin S=1/2 linear chain Heisenberg antiferromagnet copper pyrazine di…
A neutron scattering study of two-magnon states in the quantum magnet copper nitrate
D. A. Tennant, C. Broholm, D. H. Reich +7
We report measurements of the two-magnon states in a dimerized antiferromagnetic chain material, copper nitrate (Cu(NO3)2*2.5D2O). Using inelastic neutron scattering we have measur…
