On Order-Disorder ($L2_1 \to B2^\prime$) Phase Transition in Ni$_{2+x}Mn

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/19998Order-disorder phase transition in Ni$_{2+x}Mn_{1-x}$Ga Heusler alloys has been studied. It was found that the $L2_1 \to B2^{\prime}$ 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.3 pages, 3 figures, revtex4Materials ScienceOn Order-Disorder ($L2_1 \to B2^\prime$) Phase Transition in Ni$_{2+x}Mn_{1-x}$Ga Heusler Alloystext
