Abstract : The Fermi surface of Nb3Sn has been derived form an APW band calculation. de Haas-van Alphen dHvA oscillations have been observed in Nb3Sn and V3Si which give a consistent FS description. Using single crystals of high resistance ratio-s and magnetic fields up to 400 kOe, dHvA oscillations have been seen in the normal state for both specimens. New features of the Fermi surface include osculated ellipsoidal structure around M, and a large cubical structure around Γ.
