By combining the de Haas-van Alphen experiments and band structure calculations, a flat one-dimensional Fermi surface is revealed in VGa which is characterized by a chain like arrangement of atoms. On the other hand, CoGa with the nearly cubic symmetry has pyramidal Fermi surfaces with flat {111} planes, similar to NiGa with the ideal cubic structure.
