abstract = {We used angle-resolved photoemission spectroscopy (ARPES)
and density functional theory calculations to study the
electronic structure of
$\text{Ba(Fe}_{1-x-y}\text{Co}_{x}\text{Mn}_{y})_{2}\text{As}_{2}$
for $x=0.06$ and $0\le y \le 0.07$ . From ARPES we derive
that the substitution of Fe by Mn does not lead to hole
doping, indicating a localization of the induced holes. An
evaluation of the measured spectral function does not
indicate a diverging effective mass or scattering rate near
optimal doping. Thus, the present ARPES results indicate a
continuous evolution of the quasiparticle interaction and
therefore question previous quantum critical scenarios.},
