Abstract

Order-disorder phase transition in Ni $_{2 + x} M n_{1 - x}$ Ga Heusler alloys has been studied. It was found that the $L 2_{1} \to B 2^{'}$ phase transition in Ni2+xMn1-xGa (x = 0.16 - 0.20) Heusler alloys is of second order and the temperature of this transition decreases with Ni excess.
