abstract = {We report on the influence of the Al content (from 3.5 to
$54 at.\%)$ on phase formation and magnetic properties in
FeMnCoCrAl high entropy alloy thin film libraries. Al
additions to FeMnCoCr crystallizing in the alpha-Mn
structure cause the formation of the body centered cubic
(BCC) structure. This is consistent with density functional
theory predictions as Al additions give rise to a larger
stability for the BCC phase compared to the face centered
cubic phase (FCC) which can be rationalized by the formation
of a pseudogap at the Fermi level indicating the
stabilization of the BCC phase over the FCC phase. Al
additions to paramagnetic FeMnCoCr induce ferromagnetism.
The largest saturation magnetization was measured for the
film containing $8 at.\%$ of Al. As the concentration of
non-ferromagnetic Al is increased beyond $8 at.\%,$ the
number density of the ferromagnetic species is decreased
causing a concomitant decrease in magnetization. This trend
is consistent with ab initio predictions of the Al
concentration induced changes in the magnetic moment. Based
on the experimental and theoretical results presented here
the effect of the Al concentration on the phase formation
and the magnetic properties of FeMnCoCrAl thin film library
can be rationalized.},
