Spin polarization and magnetic dichroism in photoemission from core and valence states in localized magnetic systems .4. Core-hole polarization in resonant photoemission
Autor: vanderLaan, G, Thole, BT
Publikováno v: Physical Review. B: Condensed Matter and Materials Physics, 52(21), 15355-15363. AMER PHYSICAL SOC
A simple theory is presented for core-hole polarization probed by resonant photoemission in a two-steps approximation. After excitation from a core level to the valence shell, the core hole decays into two shallower core holes under emission of an el

Publikováno v: Solid State Communications, 92(5), 427-431. PERGAMON-ELSEVIER SCIENCE LTD
The angular distribution of photoelectrons from a core level or localized valence level excited with circularly or linearly polarized Xrays is shown to contain the complete one-electron information of the ground state of a magnetic polarized atom. We

MAGNETIC-X-RAY DICHROISM - GENERAL FEATURES OF DIPOLAR AND QUADRUPOLAR SPECTRA
Autor: CARRA, P, KONIG, H, THOLE, BT, ALTARELLI, M
Publikováno v: Physica B, 192(1-2), 182-190. ELSEVIER SCIENCE BV
Sum rules are derived for dipolar linear and quadrupolar circular dichroism in the X-ray region. They relate the intensity of the dichroic signal to the ground state expectation values of orbital and spin dependent effective operators, which act on t

SPIN POLARIZATION AND MAGNETIC DICHROISM IN PHOTOEMISSION FROM CORE AND VALENCE STATES IN LOCALIZED MAGNETIC SYSTEMS .2. EMISSION FROM OPEN-SHELLS
Autor: VANDERLAAN, G, THOLE, BT
Publikováno v: Physical Review. B: Condensed Matter and Materials Physics, 48(1), 210-223. AMER PHYSICAL SOC
With the use of many-particle theory general equations are derived for the six fundamental spectra, which are special linear combinations of the spin-polarized photoemission spectra measured with left-, Z-, and right-circularly polarized radiation. T

X-RAY CIRCULAR-DICHROISM AND LOCAL MAGNETIC-FIELDS
Autor: CARRA, P, THOLE, BT, ALTARELLI, M, WANG, XD
Publikováno v: Physical Review Letters, 70(5), 694-697. AMER PHYSICAL SOC
Sum rules are derived for the circular dichroic response of a core line (CMXD). They relate the intensity of the CMXD signal to the ground-state expectation value of the magnetic field operators (orbital, spin, and magnetic dipole) of the valence ele

SURFACE ORBITAL MAGNETIC-MOMENT OF FERROMAGNETIC NICKEL STUDIED BY MAGNETIC CIRCULAR-DICHROISM IN NI 3P CORE LEVEL PHOTOEMISSION
Autor: VANDERLAAN, G, HOYLAND, MA, SURMAN, M, FLIPSE, CFJ, THOLE, BT
Publikováno v: Physical Review Letters, 69(26), 3827-3830. AMER PHYSICAL SOC
The Ni 3p photoemission of ferromagnetic nickel shows a magnetic circular dichroism which is much larger than expected from the value of the bulk orbital moment. We argue that this can only be explained when the orbital moment at the surface is stron

The observed enhancement in the 3d, 3p, and 3s photoemission structures at resonance with the 2p absorption edge of nickel is analyzed using a cluster calculation including multiplet structure. The result strongly supports the view of a localized ele
