The ground state phases of orbitally degenerate spinel oxides
I review the microscopic spin-orbital Hamiltonian and ground state properties of spin one-half spinel oxides with threefold t2g orbital degeneracy. It is shown that for any orbital configuration a ground state of corresponding spin only Hamiltonian is infinitely degenerate in the classical limit. The extensive classical degeneracy is lifted by the quantum nature of the spins, an effect similar ...
متن کاملDFT-based studies on the Jahn-Teller effect in 3d hexacyanometalates with orbitally degenerate ground states.
The topology of the ground-state potential energy surface of M(CN)(6) with orbitally degenerate (2)T(2g) (M = Ti(III) (t(2g)(1)), Fe(III) and Mn(II) (both low-spin t(2g)(5))) and (3)T(1g) ground states (M = V(III) (t(2g)(2)), Mn(III) and Cr(II) (both low-spin t(2g)(4))) has been studied with linear and quadratic Jahn-Teller coupling models in the five-dimensional space of the epsilon(g) and tau...
متن کاملDegenerate ground-state lattices of membrane inclusions.
Particles that are embedded in fluid membranes or plates can induce bending if they impose a nonzero angle of contact. This bending mediates complicated effective particle-particle interactions. In the absence of tension, these interactions are nonpairwise additive and can result in clusters of particles with specific configurations that give rise to zero total membrane bending energy. Here, we...
متن کاملInterplay of orbitally polarized and magnetically ordered phases in doped transition metal oxides
We investigate the magnetic instabilities of the two-dimensional model of interacting eg electrons for hole doping away from two electrons per site in the mean-field approximation. In particular, we address the occurrence of orbitally polarized states due to the inequivalent orbitals, and their interplay with ferromagnetic and antiferromagnetic spin order. The role played by the Hund’s exchange...
متن کاملThe ground state of two - hole centres in oxides
We discuss the nature of the ground state of the V centre in ionic oxides, where two holes are trapped by a cation vacancy. Experiment appears to indicate an S = 1 ground state for B e 0 and A1,0, and possibly ZnO, with S = 0 in MgO and CaO. Simple theoretical arguments suggest S = 0. We show that a weak admixture of [0°02-] configurations into the dominant [O-0-1 configuration can explain the ...
