The transport properties of a magnetic two-dimensional electron gas consisting of a modulation doped n-type quantum well, QW, have been investigated. By analyzing the Shubnikov-de Haas oscillations and the node positions of their beating patterns, we have been able to separate the gate-voltage-dependent Rashba spin-orbit splitting from the temperature-dependent giant Zeeman splitting. It has been experimentally demonstrated that the Rashba spin-orbit splitting is larger than or comparable to the sp-d exchange-interaction–induced giant Zeeman splitting in this magnetic 2DEG even at moderately high magnetic fields.
