Neutron scattering from a coordination polymer quantum paramagnet
(American Physical Society, 2006-09-01)
Inelastic neutron scattering measurements are reported for a powder sample of the spin-1/2 quantum paramagnet Cu(quinoxaline)Br2. Magnetic neutron scattering is identified above an energy gap of 1.9 meV. Analysis of the ...
Quantum criticality in an organic magnet
(American Physical Society, 2006-06-30)
Exchange interactions between S=½ sites in piperazinium hexachlorodicuprate produce a frustrated bilayer magnet with a singlet ground state. We have determined the field-temperature phase diagram by high field magnetization ...
