Query: Vectorial spin-polarization detection in multichannel spin-resolved
  photoemission spectroscopy using an Ir(001) imaging spin filter   We report on spin- and angular resolved photoemission spectroscopy using a
high-resolution imaging spin filter based on a large Ir(001) crystal enhancing
the effective figure of merit for spin detection by a factor of over $10^3$
compared to standard single channel detectors. Furthermore, we review the spin
filter preparation, and its lifetime. The spin filter efficiency is mapped on a
broad range of scattering energies and azimuthal angles. Large spin filter
efficiencies are observed for the spin component perpendicular as well as
parallel to the scattering plane depending on the azimuthal orientation of the
spin filter crystal. A spin rotator capable of manipulating the spin direction
prior to detection complements the measurement of three observables, thus
allowing for a derivation of all three components of the spin polarization
vector in multichannel spin polarimetry. The experimental results nicely agree
with spin-polarized low energy electron diffraction calculations based on a
fully relativistic multiple scattering method in the framework of
spin-polarized density functional theory.
