    • In our case no pump laser saturates the absorption, but a faster second relaxation channel becomes effective.

    • 0 which indicates a small internal dipolar field λM ≈ 0.04-0.05 T; we have included it in our calculations.

    • note
    • At low temperatures, we observe a much faster relaxation as compared to previous data (Refs. 2,5), because in polycrystalline samples a noticeable transverse component of the magnetic field leads to an increase of the tunneling splitting, and relaxation rate. At higher temperatures the tunneling occurs via excited states with a higher initial tunneling splitting and the effect of the transverse magnetic field diminishes; hence the different data coverge.
