Modern techniques for the measurement of the de Haas-van Alphen effect now allow many properties of the Fermi surface to be determined with great precision. In addition to the traditional measurements of extremal cross-sectional areas, measurements of effective cyclotron mass, orbital g factor, and Dingle temperature have been made in palladium and platinum. From these measurements the Fermi radii, Fermi velocities, and density of states are calculated. Comparison of these data with recent band structure calculations gives estimates of the magnitude of the many-body corrections. Such corrections include not only the effects of electron-electron and electron-phonon interactions but also the effects of the exchange enhancement due to short-lived spin fluctuations.
