Magnetization measurements on zero field cooled (ZFC) and field cooled (FC) samples as a function of temperature where made on Fe0.70-xMn xAl0.30 alloys with 0≤x≤0.10. Our data show the existence of two regimes of the spin glass temperature Tf when increasing the concentration x of the Mn atoms. We found that Tf decreases slowly with increasing x up to x=0.06 and then shows a rapid linear decrease above this concentration. The existence of two regimes of T f behavior with x may be attributed to the disappearance of ferromagnetic clusters which exist for low values of x (x<0.06). Compared to the Mn-free alloy, the relative changes in Tf are bigger and exceed 40% at x=0.10. The second regime (x>0.06) is associated with more influence of x on Tf.
