Complex magnetic order in the kagome staircase compound Co3V2O8
Y. Chen, J. W. Lynn, Q. Huang +9
Co3V2O8 (CVO) has a geometrically frustrated magnetic lattice, a Kagome staircase. The crystal structure consists of two inequivalent Co sites, one-dimensional chains of Co(2) spin…
Field dependence of magnetic ordering in Kagome-staircase compound Ni3V2O8
M. Kenzelmann, A. B. Harris, A. Aharony +11
We present powder and single-crystal neutron diffraction and bulk measurements of the Kagome-staircase compound Ni3V2O8 (NVO) in fields up to 8.5T applied along the c-direction. (T…
Orbital order, anisotropic spin couplings, and the spin-wave spectrum of the ferromagnetic Mott insulator YTiO3
Robert Schmitz, Ora Entin-Wohlman, Amnon Aharony +1
Using a point-charge calculation of the electrostatic crystal field, we determine the non-degenerate orbital ground state of the ferromagnetic Mott insulator YTiO3, which is found…
The spin-wave spectrum of the Jahn-Teller system LaTiO3
Robert Schmitz, Ora Entin-Wohlman, Amnon Aharony +2
We present an analytical calculation of the spin-wave spectrum of the Jahn-Teller system LaTiO3. The calculation includes all superexchange couplings between nearest-neighbor Ti io…
The magnetic structure of the Jahn-Teller System LaTiO3
Robert Schmitz, Ora Entin-Wohlman, Amnon Aharony +2
We investigate the effect of the experimentally observed Jahn-Teller distortion of the oxygen octahedra in LaTiO3 on the magnetic exchange. We present a localized model for the eff…
Competing Magnetic Phases on a "Kagome Staircase"
G. Lawes, M. Kenzelmann, N. Rogado +11
We present thermodynamic and neutron data on Ni_3V_2O_8, a spin-1 system on a kagome staircase. The extreme degeneracy of the kagome antiferromagnet is lifted to produce two incomm…
