Abstract: The effect of large plastic deformations at room temperature in a Bridgman anvil cell on the specific saturation magnetization of the DO$_3$-type ordered (Fe-24 at % Al) alloy has been revealed. It has been found that torsion at high pressure and certain deformation parameters results in the complete suppression of long-range order in the alloy and in the corresponding increase in the specific saturation magnetization by 11% with respect to the equilibrium state. A theoretical model qualitatively describing the revealed phenomenon has been proposed.
