With the addition of Gd, the Ni56Mn18.8Ga24.5 Gd0.7 alloy exhibits non-modulated martensite phase at room temperature. From the illustration of Gd microstructure, it can be found that Gd exists along the subgrain boun...
Composition and electron concentration dependence of transformation temperature in Ni2+x+y Mn1-xGa1-y, Ni2+x Mn1-x Ga alloys with first order magnetic transition were studied. For Ni2 + x + y Mn1- x Ga1-y alloys,...
