The temperature dependence is studied of the extent of the long-range order and size of the domain in the alloy Ni3Mn, alloyed with small additions (a few atoms percent) of aluminum and copper. It is shown that A1 stabilizes the superlattice of Ni3Mn but Cu destroys it. In alloys of Ni3(Mn, Al) a monotonic effect is observed of the aluminum concentration in the alloy on the nature of the phase transition.
