Gd5Si2.05− x Ge 1.95− x Ni 2 x (2x = 0.08, 0.1) alloys were prepared by arc melting followed by annealing at 1273 K for 96 h. Mixed monoclinic Gd5Si2 Ge 2-type phase, orthorhombic Gd5Si4-type phase, and a small amount of Gd5Si3-type phase were obtained in these alloys. Gd5Si2.01 Ge 1.91 Ni 0.08 allo...
