The Effect of Dopants on Magnetic Properties of the Ordered Fe_65-xAl_35-yM_x,y (M_x,y=Ga,B,V; X,Y=5,10) Alloys

Abstract:

The results of X-ray diffraction, complex in-field (up to 9 T) and temperature (5300 К) Mössbauer and magnetometric studies of the ordered Fe₆₅Al_35-хM_х (M=Ga, B; x=0,5,10) and Fe_65-хV_xAl₃₅ (x=5,10) alloys are presented. Analysis of the magnetometry studies shows that the systems Fe₆₅Al₃₅ и Fe₆₅Al_35-хGa_х (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 Fe₆₅Al₃₅ alloy. The boron addition transforms the magnetic state of the initial alloy Fe₆₅Al₃₅ into a ferromagnetic one exhibiting high magnetic characteristics. Substitution of V for Fe in the ternary alloys Fe_65-хV_xAl₃₅ results in reduction of magnetic characteristics and collapsing of ⁵⁷Fe hyperfine magnetic filed.
