Abstract

The Fermi surface of two A15 compounds, Nb₃Ir and Cr₃Si, has been determined by positron annihilation using both 1D and 2D angular correlation techniques. These results are compared with those obtained by linear muffin-tin orbitals band structure calculations. We point out some differences in the Fermi surface topology between high- and low- T_c A15 materials.
