Query: The role of electron confinement in Pd films for the oscillatory
  magnetic anisotropy in an adjacent Co layer   We demonstrate the interplay between quantum well states in Pd and the
magnetic anisotropy in Pd/Co/Cu(001) by combined scanning tunneling
spectroscopy (STS) and magneto optical Kerr effect (MOKE) measurements. Low
temperature scanning tunneling spectroscopy reveals occupied and unoccupied
quantum well states (QWS) in atomically flat Pd films on Co/Cu(001). These
states give rise to sharp peaks in the differential conductance spectra. A
quantitative analysis of the spectra reveals the electronic dispersion of the
Pd(001) d-band ($\Delta$$_5$-type) along the $\Gamma$-X direction.
\textit{In-situ} MOKE experiments on Pd/Co/Cu(1, 1, 13) uncover a periodic
variation of the in-plane uniaxial magnetic anisotropy as a function of Pd
thickness with a period of 6 atomic layers Pd. STS shows that QWS in Pd cross
the Fermi level with the same periodicity of 6 atomic layers. Backed by
previous theoretical work we ascribe the variation of the magnetic anisotropy
in Co to QWS in the Pd overlayer. Our results suggest a novel venue towards
tailoring uniaxial magnetic anisotropy of ferromagnetic films by exploiting QWS
in an adjacent material with large spin-orbit coupling.
