abstract = {Magnetic anisotropy controls the orientational stability
and switching properties of magnetic states, and therefore
plays a central role in spintronics. First-principles
density functional theory calculations are able, in most
cases, to provide a satisfactory description of bulk and
interface contributions to the magnetic anisotropy of
particular film/substrate combinations. In this paper we
focus on achieving a simplified understanding of some trends
in interfacial magnetic anisotropy based on a simple
tight-binding model for quasiparticle states in a
heavy-metal/ferromagnetic-metal bilayer film. We explain how
to calculate the magnetic anisotropy energy of this model
from the quasiparticle spin susceptibility, compare with
more conventional approaches using either a perturbative
treatment of spin-orbit interactions or a direct calculation
of the dependence of the energy on the orientation of the
magnetization, and show that the magnetic anisotropy can be
interpreted as a competition between a Fermi sea term
favoring perpendicular anisotropy and a Fermi surface term
favoring in-plane anisotropy. Based on this finding, we
conclude that perpendicular magnetic anisotropy should be
expected in an itinerant electron thin film when the spin
magnetization density is larger than the product of the band
exchange splitting and the Fermi level density of states of
the magnetic state.},
