  This study reports the first observation of ferromagnetic (FM) order in the
non-Au-based approximant crystals (ACs) using a novel approach whereby a total
electron-per-atom (e/a) ratio of the spin-glass Ga50Pd36Gd14 1/1 AC is lowered
by simultaneously substituting certain ratios of a tri-valent Ga and a
zero-valent Pd by a mono-valent Au. The emergence of FM order by this method
was confirmed via magnetic susceptibility, magnetization, and specific heat
measurements. The findings of this study open up vast opportunities in
developing long-range magnetic orders from stoichiometric ACs, quasicrystals,
and even other RKKY compounds with spin-glass ground state.
