16. The excitation power density was verified to be low enough to avoid direct or indirect carrier induced heating of the Mn2+ spin system in the sample.

18. The time resolution is limited by the width of the observation window, and a possibly nonideal rectangular shape of the current pulse has to be taken into account.
