Ferromagnetic fluctuation and superconductivity in Na0.35CoO2·1.3H2O:FLEX study ofmulti-orbital Hubbardmodel
Spin and charge fluctuations and superconductivity in Na0.35CoO2·1.3H2O are studied based on a multi-orbital Hubbard model. By applying the fluctuation exchange (FLEX) approximation, we show that the Hund’s-rule coupling between the Co t2g orbitals causes ferromagnetic spin fluctuation. Triplet pairing is favored by this ferromagnetic fluctuation on the hole-pocket band. We propose that, in Na0...
متن کاملUnusual ferromagnetism enhancement in ferromagnetically optimal manganite La0.7−yCa0.3+yMn1−yRuyO3 (0≤y<0.3): the role of Mn-Ru t2g super-exchange
The eg-orbital double-exchange mechanism as the core of physics of colossal magnetoresistance (CMR) manganites is well known, which usually covers up the role of super-exchange at the t2g-orbitals. The role of the double-exchange mechanism is maximized in La0.7Ca0.3MnO3, leading to the concurrent metal-insulator transition and ferromagnetic transition as well as CMR effect. In this work, by a s...
متن کاملTheory of orbital state and spin interactions in ferromagnetic titanates
A spin-orbital superexchange Hamiltonian in a Mott insulator with t2g orbital degeneracy is investigated. More specifically, we focus on a spin ferromagnetic state of the model and study a collective behavior of orbital angular momentum. Orbital order in the model occurs in a nontrivial way—it is stabilized exclusively by quantum effects through the order-from-disorder mechanism. Several energe...
متن کاملMagnetic and orbital correlations in a two-site molecule
We analyze the role of orbital degeneracy in possible magnetic and orbital instabilities by solving exactly a two-site molecule with two orbitals of either eg or t2g symmetry at quarter-filling. As a generic feature of both models one finds that the spin and orbital correlations have opposite signs in the low temperature regime when the orbitals are degenerate, in agreement with the Goodenough-...
متن کاملCoulomb correlations and orbital polarization in the metal-insulator transition of VO2
The quasiparticle spectra in the metallic rutile and insulating monoclinic phases of VO2 are shown to be dominated by local Coulomb interactions. In the rutile phase the small orbital polarization among V 3d t2g states leads to weak static but strong dynamical correlations. In the monoclinic phase the large 3d orbital polarization caused by the VuV Peierls distortion gives rise to strong static...
