    • Broken parity and a chiral ground state in the frustrated magnet CdCr2O4 

      Chern, Gia-Wei; Fennie, C. J.; Tchernyshyov, Oleg (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 ...
