Magnetization measurements on zero field cooled (M_{ZFC}) and field cooled (M_{FC}) with temperature T were made on Fe_{0.7-x}M_xAl_{0.30} alloys (where M = Co or M = V). Compared to Co and V free alloy Fe_{0.7}Al_{0.30}, our results revealed that an addition of small amount of M = Co with 0≤ x≤0.10 shows linear decrease in the transition temperature T_f as x increases. Addition of small amount of M = V with 0≤ x≤0.1 shows gradual decrease in T_f with increasing x. The relative changes in T_f show that an addition of V atoms is of more significance than addition of Co atoms. There is a twofold decrease which could be attributed to the ferromagnetic nature of Co atoms and to the random fields.
