Abstract: The effect of atomic disordering and deviation from the Ni$_2$MnGa stoichiometric composition on the low-temperature properties of alloys with magnetically controlled shape memory effect is studied. The specific features of the magnetic, galvanomagnetic, and electrical properties of alloys with magnetically controlled shape memory effect are discussed. The specific features of the magnetic, galvanomagnetic, and electrical properties of alloys i$_{50}$Mn$_{25}$Ga$_{25}$, Ni$_{54}$Mn$_{21}$Ga$_{25}$, and Ni$_{50}$Mn$_{28.5}$Ga$_{21.5}$ in the temperature range 2 $\le T\le$ 80 K under magnetic fields $H\le$ 12 MA/m are studied.
