    • note
    • The measurements of the magnetic field induced MOKE between 1.4 and 2.2 eV (see inset of Fig. 3) clearly demonstrate that the oscillatory behavior in Fig. 2 is caused by an optical interference. In spite of this fact, the spectra of the two effects are affected by the interference in a similar way (see Fig. 2) and thus can be compared.

    • note
    • Note that the strong interaction between the spins of Mn and that of holes is responsible for ferromagnetism in (Ga,Mn)As. Therefore the absence of magnetic field dependence of the photoinduced MOKE once again demonstrates that the observed signal cannot be assigned to the photoexcited holes. Otherwise, the strong coupling between the spins of holes and those of Mn ions should result in some modification of the temporal behavior of the MOKE, even if the damping of the homogeneous precession is fast.
