The effect of Zn substitution on the structure and magnetic properties of τ-MnAl has been investigated sys-tematically. It is found that Zn substitution can stabilize the structure of τ-phase and thus a significant amount of τ-phase can be produced. Zn increases the coercivity and saturation magnetization of the τ-MnAl but reduces the Currie temperature. However, excess Zn is detrimental to the magnetic parameters. The optimum magnetic performance was found in samples with Zn substitution to 2.9% Mn atoms and 3.5% Al atoms, respectively.
