Spin-split de Haas–van Alphen oscillations in two-dimensional (2D) electron systems are studied experimentally and theoretically. It is shown that large second harmonic observed at low temperatures in the quasi-2D organic metal κ-(ET)2I3 (ET≡BEDT-TTF) is due to the effect of spin-splitting close to its maximal value. The calculated shape and amplitudes of magnetization oscillations are in remarkable quantitative agreement with the experimental ones.
