Abstract
A first-principle description of the
magneto-optical Kerr effect (MOKE)
of ultra-thin surface layer systems is presented, that
is based on the concept of non-local
layer-resolved optical conductivity and the
corresponding solution of the
Maxwell equations.
This powerful approach allowed a detailed investigation
of the system Au(001)/
nFe/
mAu that shows
pronounced quantum-confinement effects.
In particular insight into the spatial origin of
magneto-optical properties
was obtained and
the reliability of simplified approaches
could be checked that way
for this important prototype
surface layer system.
