Spin-resolved mapping of spin contribution to exchange-correlation holes.

چکیده
By means of spin-polarized electron coincidence spectroscopy we explore the fundamental issue of spin-resolved contributions to the exchange-correlation hole in many-electron systems. We present a joint experimental and theoretical study of correlated electron pair emission from a ferromagnetic Fe(001) surface induced by spin-polarized low-energy electrons. We demonstrate that the contribution to the exchange-correlation hole due to exchange is more extended than the contribution due to the screened Coulomb interaction.

A spin-polarized scheme for obtaining quasi-particle energies within the density functional theory
We discuss an efficient scheme for obtaining spin-polarized quasi-particle excitation energies within the general framework of the density functional theory (DFT). Our approach is to correct the DFT eigenvalues via the electrostatic energy of a majority or minority spin electron resulting from its interaction with the associated exchange and correlation holes by using appropriate spin-resolved ...
متن کاملMAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON
The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...
متن کاملOptical properties of spin-coated Er-doped Ga1As39S60 Chalcogenide thin films
Spin-coating of Chalcogenide glasses is a cost-effective and flexible method to produce thin films applicable in photonics. In this paper Er was doped into Ga1As39S60 glass by melt quenching technique and solutions for spin coating were prepared from glass powders dissolved in Propylamine and Ethylendiamine. Substrates used were microscopic slides (refractive index of about 1.51). Applied layer...
متن کاملBeam normal spin asymmetry in the quasireal Compton scattering approximation
The two-photon exchange contribution to the single spin asymmetries with the spin orientation normal to the reaction plane is discussed for elastic electron-proton scattering in the equivalent photon approximation. In this case, the hadronic part of the two-photon exchange amplitude describes real Compton scattering (RCS). We show that in the case of the beam normal spin asymmetry this approxim...
متن کاملSpin-resolved off-normal photoemission from xenon adsorbates in comparison with free-atom photoionization
Energy-, angle, and spin-resolved photoemission studies on adsorbate systems were up to now restricted to the highly symmetrical set up of normal light incidence and normal photoelectron emission [I-3]. By use of the circularly polarized synchrotron radiation at BESSY in Berlin, the photoemission from the valence bands of rare gas adlayers on metal single crystals yielded a complete spin polari...
