A method for determining an activation sequence for a magnetic resonance device is provided. The activation sequence includes single pulses to be emitted simultaneously for a plurality of individually activatable high-frequency transmission channels. The method includes determining an amplitude and a phase of a plurality of square-wave subpulses, of which the single pulse is composed, by a pulse optimization method for a predefined target magnetization for each of the single pulses. The method also includes determining optimized, layer-selective subpulses for each square-wave subpulse of the plurality of square-wave subpulses while retaining phase and integral of the square-wave subpulse with regard to a bandwidth of the plurality of square-wave subpulses and/or the quality of a profile of a layer to be excited.
