Abstract
The de Haas-van Alphen effect is studied in heavy-fermion antiferromag nets near the spin-flip transition is studied. It is shown that the st rong increase occurring in the amplitude of oscillations near the spin -flip point in an increasing magnetic held, as observed experimentally in CeCu2Si2, can be explained by strong single-site correlations and magnetic ordering in the subsystem of localized electronic states.
