Magnetic and orbital ordering in the spinel MnV2O4.
Neutron inelastic scattering and diffraction techniques have been used to study the MnV2O4 spinel system. Our measurements show the existence of two transitions to long-range ordered ferrimagnetic states, the first collinear and the second noncollinear. The lower temperature transition, characterized by development of antiferromagnetic components in the basal plane, is accompanied by a tetragon...
متن کاملUniversality in one-dimensional orbital wave ordering in spinel and related compounds: an experimental perspective
Recent state-of-the-art crystallographic investigations of transition metal spinel compounds have revealed that the d-orbital charge carriers undergo ordering transitions with the formation of local ‘molecular bonding’ units such as dimers in MgTi2O4, octomers in CuIr2S4, and heptamers in AlV2O4. Herein, we provide a unifying scheme involving one-dimensional (1D) orbital wave (OW) ordering appl...
متن کاملOrbital-ordering transition in Sr2VO4.
Temperature-dependent dc susceptibility and x-ray powder diffraction on a pure tetragonal sample of Sr(2)VO(4) show an antiferromagnetic orbital-ordering transition at T(oo) = 97 K, in which the occupied orbitals lie along the c axis. The unusual broadening of the x-ray Bragg peaks throughout the orbital-ordering transition temperature region indicates that this process occurs in stages, and th...
متن کاملOrbital ordering and one-dimensional magnetic correlation in vanadium spinel oxides AV2O4 (A= Zn, Mg, or Cd)
We present our theoretical results on the mechanism of two transitions in vanadium spinel oxides AV2O4 (A=Zn, Mg, or Cd) in which magnetic V cations constitute a geometrically-frustrated pyrochlore structure. We have derived an effective spin-orbital-lattice coupled model in the strong correlation limit of the multiorbital Hubbard model, and applied Monte Carlo simulation to the model. The resu...
متن کاملOrbital Ordering and Orbital Fluctuations in Transition Metal Oxides
We summarize some characteristic features of the frustrated magnetic interactions in spin-orbital models adequate for cubic transition metal oxides with orbital degeneracy. A generic tendency towards dimerization, found already in the degenerate Hubbard model, is confirmed for t2g but not for eg systems. In the t2g case the quantum orbital fluctuations are more pronounced and contribute to a st...
