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 ...
Broken parity and a chiral ground state in the frustrated magnet CdCr2O4
(American Physical Society, 2006-08-01)
We present a model describing the lattice distortion and incommensurate magnetic order in the spinel CdCr2O4, a good realization of the Heisenberg 'pyrochlore' antiferromagnet. The magnetic frustration is relieved through ...
Field dependence of magnetic ordering in Kagome-staircase compound Ni3V2O8
(American Physical Society, 2006-07-01)
We present powder and single-crystal neutron diffraction and bulk measurements of the Kagome-staircase compound Ni3V2O8 (NVO) in fields up to 8.5 T applied along the c direction. (The Kagome plane is the a-c plane.) This ...
