Spin, Orbital, and Spin-Orbital Polarons in Transition Metal Oxides
I give a brief overview of a polaron formation in three distinct transition metal oxides: (i) spin polaron when a hole is added to the antiferromagnetic (AF) ordered plane in La2CuO4, (ii) orbital polaron when a hole is added to the alternating orbital (AO) ordered plane in LaMnO3, and (iii) spin-orbital polaron when a hole is added to the AF and AO ordered plane in LaVO3. Comparison of the dis...
متن کاملMagnetic properties of spin-orbital polarons in lightly doped cobaltates.
We present a numerical treatment of a spin-orbital-polaron model for NaxCoO2 at small hole concentration (0.7 < x 1). We demonstrate how the polarons account for the peculiar magnetic properties of this layered compound: They explain the large susceptibility; their internal degrees of freedom lead both to a negative Curie-Weiss temperature and yet to a ferromagnetic intralayer interaction, ther...
متن کاملSpin–Orbital Physics in Transition Metal Oxides
We present the main features of the spin-orbital superexchange which describes the magnetic and optical properties of Mott insulators with orbital degrees of freedom. In contrast to the SU(2) symmetry of spin superexchange, the orbital part of the superexchange obeys the lower cubic symmetry of the lattice and is intrinsically frustrated. This intrinsic frustration and spin-orbital entanglement...
متن کاملApical oxygens and correlation strength in electron- and hole-doped copper oxides
We use the local-density approximation in combination with the dynamical mean-field theory to carry out a comparative investigation of a typical electron-doped and a typical hole-doped copper oxide, NCCO, and LSCO, respectively. The parent compounds of both materials are strongly correlated electron systems in the vicinity of the metal to charge-transfer insulator transition. In NCCO the magnet...
متن کاملSpin structures of tetragonal lamellar copper oxides.
The spin Hamiltonian of tetragonal lamellar antiferromagnets is shown to contain several novel anisotropies. Symmetry allows bond-dependent anisotropic exchange interactions, which lead to (a) interplane mean-field coupling and (b) an in-plane anisotropy which vanishes classically but arises from quantum zero point energy (QZPE). A similar QZPE involving the interplane isotropic interaction pre...
