Query: Control of site occupancy by variation of the Zn and Al content in
  NiZnAl ferrite epitaxial films with low magnetic damping   The structural and magnetic properties of Zn/Al doped nickel ferrite thin
films can be adjusted by changing the Zn and Al content. The films are
epitaxially grown by reactive magnetron sputtering using a triple cluster
system to sputter simultaneously from three different targets. Upon the
variation of the Zn content the films remain fully strained with similar
structural properties, while the magnetic properties are strongly affected. The
saturation magnetization and coercivity as well as resonance position and
linewidth from ferromagnetic resonance (FMR) measurements are altered depending
on the Zn content in the material. The reason for these changes can be
elucidated by investigation of the x-ray magnetic circular dichroism spectra to
gain site and valence specific information with elemental specificity.
Additionally, from a detailed investigation by broadband FMR a minimum in
g-factor and linewidth could be found as a function of film thickness.
Furthermore, the results from a variation of the Al content using the same set
of measurement techniques is given. Other than for Zn, the variation of Al
affects the strain and even more pronounced changes to the magnetic properties
are apparent.
