abstract = {The structural, magnetic, and Mössbauer spectral
properties of the approximant Al76Ni9Fe15 to a decagonal
Al–Ni–Fe quasicrystal, complemented by ab-initio
electronic structure and the hyperfine-interaction
parameters calculations, are reported. The approximant
studied crystallizes in the monoclinic space group C2/m with
the lattice parameters a = 15.3898(3) Å, b = 8.0840(2) Å,
c = 12.4169(2) Å, and β = 107.870(2)∘. The existence of
a pseudogap in the calculated electronic density of states
slightly above the Fermi level suggests electronic
stabilization according to the Hume-Rothery-type mechanism.
High metallicity of Al76Ni9Fe15 is predicted. Both the
Mössbauer spectra and magnetic susceptibility data indicate
that Al76Ni9Fe15 is a paramagnet down to 2.0 K. The presence
of the distribution of the electric quadrupole splitting in
the Mössbauer spectra measured in the temperature range
4.5–296.1 K is observed. The increase of the average
quadrupole splitting with decreasing temperature is well
described by a T3/2 power-law relation. The Debye
temperature of Al76Ni9Fe15 is found to be 431(3) K.},
