Theory of anisotropic superexchange in insulating cuprates.
Spin-orbit corrections to superexchange are calculated using the method of Moriya [T. Moriya, Phys. Rev. 120 91, (1960)] for two of the insulating parent compounds of the cuprate superconductors: (1) La2−xNdxCuO4 where the CuO6 octahedra forming each Cu-O layer are tilted in staggered fashion about an axis which depends on x and temperature; and (2) YBa2Cu3O6+x (x ∼ 0.4) where the Cu-O layers f...

متن کاملAnisotropic Covalency Contributions to Superexchange Pathways in Type One Copper Active Sites
Type one (T1) Cu sites deliver electrons to catalytic Cu active sites: the mononuclear type two (T2) Cu site in nitrite reductases (NiRs) and the trinuclear Cu cluster in the multicopper oxidases (MCOs). The T1 Cu and the remote catalytic sites are connected via a Cys-His intramolecular electron-transfer (ET) bridge, which contains two potential ET pathways: P1 through the protein backbone and ...
متن کاملSuperexchange-driven magnetoelectricity in magnetic vortices.
We demonstrate that magnetic vortices in which spins are coupled to polar lattice distortions via superexchange exhibit an unusually large linear magnetoelectric response. We show that the periodic arrays of vortices formed by frustrated spins on kagome lattices provide a realization of this concept; our ab initio calculations for such a model structure yield a magnetoelectric coefficient that ...
متن کاملUnconventional anisotropic s-wave superconducting gaps of the LiFeAs iron-pnictide superconductor.
We have performed high-resolution angle-resolved photoemission spectroscopy on Fe-based superconductor LiFeAs (T(c)=18 K). We reveal multiple nodeless superconducting (SC) gaps with 2Δ/k(B)T(c) ratios varying from 2.8 to 6.4, depending on the Fermi surface (FS). We also succeeded in directly observing a gap anisotropy along the FS with magnitude up to ~30%. The anisotropy is fourfold symmetric ...
