Magnetic 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 correlations and magnetic susceptibilities of lightly doped antiferromagnets
We calculate the spin correlation function and the magnetic longitudinal and transverse susceptibilities of a two-dimensional antiferromagnet doped with a small concentration of holes, in the t-J model. We find that the motion of holes generates spin fluctuations which add to the quantum fluctuations, the spin correlations decaying with the inverse of the spin distance, while increasing with do...
متن کاملPolaron Effects on the Stark Shift of a Bound Polaron in Finite Quantum Wells
We performed electron spin and nuclear magnetic resonance and inelastic neutron scattering measurements of a single crystal of lightly hole-doped La1−xSrxCoO3, x ∼ 0.002 in order to establish the origin of a surprisingly strong magnetization due to a very small Sr doping. The data provide experimental evidence for the creation at low temperatures of extended spin clusters with a large spin mult...
متن کاملVisualization of the emergence of the pseudogap state and the evolution to superconductivity in a lightly hole-doped Mott insulator
Superconductivity emerges from the cuprate antiferromagnetic Mott state with hole doping. The resulting electronic structure1 is not understood, although changes in the state of oxygen atoms seem paramount2–5. Hole doping first destroys the Mott state, yielding a weak insulator6,7 where electrons localize only at low temperatures without a full energy gap. At higher doping levels, the ‘pseudoga...
متن کاملOptically oriented and detected electron spin resonance in a lightly doped n-GaAs layer
Spin resonance of localized electrons bound to donors in a specially designed n-GaAs layer has been performed at 236 MHz and 41 mT, using circular polarized light to polarize the electrons and photoluminescence to detect the electronic polarization. The polarization was diminished under the resonance condition. The electronic g factor obtained by this measurement is 20.4160.01. The resonance li...
