  The results of X-ray diffraction, complex in-field (up to 9 T) and
temperature (5-300 K) Moessbauer and magnetometric studies of the ordered
Fe_{65}Al_{35-x}M_x (M=Ga, B; x=0,5,10) and Fe_{65-x}V_xAl_{35} (x=5,10) alloys
are presented. Analysis of the magnetometry studies shows that the systems
Fe_{65}Al_{35} and Fe_{65}Al_{35-x}Ga_x (x=5, 10) are characterized by two
different magnetic states with essentially distinguishing hysteresis loops and
AC susceptibility values. The temperature and external magnetic field values
inducing the transition from one magnetic state to another are higher in the
Ga-doped alloys than in the reference Fe_{65}Al_{35} alloy. The boron addition
transforms the magnetic state of the initial alloy Fe_{65}Al_{35} into a
ferromagnetic one exhibiting high magnetic characteristics. Substitution of V
for Fe in the ternary alloys Fe_{65-x}V_xAl_{35} results in reduction of
magnetic characteristics and collapsing of 57Fe hyperfine magnetic filed.
