Nematic order in square lattice frustrated ferromagnets
Nic Shannon, Tsutomu Momoi, Philippe Sindzingre
We present a new scenario for the breakdown of ferromagnetic order in a two-dimensional quantum magnet with competing ferromagnetic and antiferromagnetic interactions. In this, dyn…
Tomonaga-Luttinger Liquid in a Quasi-One-Dimensional S=1 Antiferromagnet Observed by the Specific Heat
M. Hagiwara, H. Tsujii, C. R. Rotundu +6
Specific heat experiments on single crystals of the S=1 quasi-one-dimensional bond-alternating antiferromagnet Ni(C_9H_24N_4)(NO_2)ClO_4, alias NTENP, have been performed in magnet…
First-principles Calculation of Effective Onsite Coulomb Interaction of 3d Transition Metals: Constrained Local Density Functional Approach with Maximally Localized Wannier Function
Kazuma Nakamura, Ryotaro Arita, Yoshihide Yoshimoto +1
We present a new ab initio method for calculating effective onsite Coulomb interactions of itinerant and strongly correlated electron systems. The method is based on constrained lo…
A metamagnetic critical point in a three dimensional frustrated antiferromagnet
Nic Shannon, Karlo Penc, Yukitoshi Motome
The competition between different forms of order is central to the problem of strong correlation. This is particularly true of frustrated systems, which frequently exist at or near…
Theory of successive transitions in vanadium spinels and order of orbitals and spins
Yukitoshi Motome, Hirokazu Tsunetsugu
We have theoretically studied successive transitions in vanadium spinel oxides with (t_2g)^2 electron configuration. These compounds show a structural transition at ~ 50K and an an…
Theory of orbital state and spin interactions in ferromagnetic titanates
G. Khaliullin, S. Okamoto
A spin-orbital superexchange Hamiltonian in a Mott insulator with orbital degeneracy is investigated. More specifically, we focus on a spin ferromagnetic state of the mode…
