Neutron irradiation experiments under magnetic fields on Fe-Ni alloys (50-50) have led to discovery of a new order-disorder transition of the type Au Cu of which the critical temperature is 320 deg C. The diffusion coefficient at temperatures of the order of 300 deg C being very low, the ordering can only be established under irradiation. The directing effect of the applied magnetic field due to the magnetic coupling of the bonds with the magnetization favors the development of the tetragonal axis in the direction of the field for the crystallites whose STA100! axis lies in the neighborhood of the direction of the field. A study on the single crystal shows that this tetragonal axis is the only axis of easy magnetization in the ordered structure. (auth)
