“…Four rare-earth ternary intermetallide compounds have been found on the isothermal sections of the system at T = 673 K [10], namely: Y(Al x Ga 1 À x ) 4 (0.65 < x < 0.6875), Y(Al x Ga 1 À x ) 4 (0.4 < x < 0.475), YAl 0.4 Ga 2.6 , Y(Al x Ga 1 À x ) 2 (0.35 < x < 0.45). In addition, regions of solid solution, which form with substitutions of Al on Ga and vice versa in the YAl 3 , YAl 2 , YGa 6 and YGa 2 intermetallide compounds, have been determined in the ternary system [10]. The magnetic susceptibility of the Y(Al x Ga 1 À x ) 4 compounds have also been reported in [11].…”
