Fe–49Co–2V alloys exhibit the highest saturation magnetic flux density among soft magnetic materials, but their high Co content increases cost and reduces workability. In this study, Fe–Co–Mn alloys were vacuum annealed to form a {001} texture through recrystallization induced by the γ→α transformation.
